mm, swap: remove fragment clusters counter
It was used for calculating the iteration number when the swap allocator wants to scan the whole fragment list. Now the allocator only scans one fragment cluster at a time, so no one uses this counter anymore. Remove it as a cleanup; the performance change is marginal: Build linux kernel using 10G ZRAM, make -j96, defconfig with 2G cgroup memory limit, on top of tmpfs, 64kB mTHP enabled: Before: sys time: 6278.45s After: sys time: 6176.34s Change to 8G ZRAM: Before: sys time: 5572.85s After: sys time: 5531.49s Link: https://lkml.kernel.org/r/20250806161748.76651-3-ryncsn@gmail.com Signed-off-by: Kairui Song <kasong@tencent.com> Reviewed-by: Nhat Pham <nphamcs@gmail.com> Acked-by: Chris Li <chrisl@kernel.org> Cc: Baoquan He <bhe@redhat.com> Cc: Barry Song <baohua@kernel.org> Cc: "Huang, Ying" <ying.huang@linux.alibaba.com> Cc: Kemeng Shi <shikemeng@huaweicloud.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> |

mm, swap: only scan one cluster in fragment list
Patch series "mm, swap: improve cluster scan strategy", v2. This series improves the large allocation performance and reduces the failure rate. Some design of the cluster alloactor was later found to be improvable after thorough testing. The allocator spent too much effort scanning the fragment list, which is not helpful in most setups, but causes serious contention of the list lock (si->lock). Besides, the allocator prefers free clusters when searching for a new cluster due to historical reasons, which causes fragmentation issues. So make the allocator only scan one cluster for high order allocation, and prefer nonfull cluster. This both improves the performance and reduces fragmentation. For example, build kernel test with make -j96 and 10G ZRAM with 64kB mTHP enabled shows better performance and a lower failure rate: Before: sys time: 11609.69s 64kB/swpout: 1787051 64kB/swpout_fallback: 20917 After: sys time: 5587.53s 64kB/swpout: 1811598 64kB/swpout_fallback: 0 System time is cut in half, and the failure rate drops to zero. Larger allocations in a hybrid workload also showed a major improvement: 512kB swap failure rate: Before: swpout:11663 swpout_fallback:1767 After: swpout:14480 swpout_fallback:6 2M swap failure rate: Before: swpout:24 swpout_fallback:1442 After: swpout:1329 swpout_fallback:7 This patch (of 3): Fragment clusters were mostly failing high order allocation already. The reason we scan it through now is that a swap slot may get freed without releasing the swap cache, so a swap map entry will end up in HAS_CACHE only status, and the cluster won't be moved back to non-full or free cluster list. This may cause a higher allocation failure rate. Usually only !SWP_SYNCHRONOUS_IO devices may have a large number of slots stuck in HAS_CACHE only status. Because when a !SWP_SYNCHRONOUS_IO device's usage is low (!vm_swap_full()), it will try to lazy free the swap cache. But this fragment list scan out is a bit overkill. Fragmentation is only an issue for the allocator when the device is getting full, and by that time, swap will be releasing the swap cache aggressively already. Only scanning one fragment cluster at a time is good enough to reclaim already pinned slots, and move the cluster back to nonfull. And besides, only high order allocation requires iterating over the list, order 0 allocation will succeed on the first attempt. And high order allocation failure isn't a serious problem. So the iteration of fragment clusters is trivial, but it will slow down large allocation by a lot when the fragment cluster list is long. So it's better to drop this fragment cluster iteration design. Test on a 48c96t system, build linux kernel using 10G ZRAM, make -j48, defconfig with 768M cgroup memory limit, on top of tmpfs, 4K folio only: Before: sys time: 4432.56s After: sys time: 4430.18s Change to make -j96, 2G memory limit, 64kB mTHP enabled, and 10G ZRAM: Before: sys time: 11609.69s 64kB/swpout: 1787051 64kB/swpout_fallback: 20917 After: sys time: 5572.85s 64kB/swpout: 1797612 64kB/swpout_fallback: 19254 Change to 8G ZRAM: Before: sys time: 21524.35s 64kB/swpout: 1687142 64kB/swpout_fallback: 128496 After: sys time: 6278.45s 64kB/swpout: 1679127 64kB/swpout_fallback: 130942 Change to use 10G brd device with SWP_SYNCHRONOUS_IO flag removed: Before: sys time: 7393.50s 64kB/swpout:1788246 swpout_fallback: 0 After: sys time: 7399.88s 64kB/swpout:1784257 swpout_fallback: 0 Change to use 8G brd device with SWP_SYNCHRONOUS_IO flag removed: Before: sys time: 26292.26s 64kB/swpout:1645236 swpout_fallback: 138945 After: sys time: 9463.16s 64kB/swpout:1581376 swpout_fallback: 259979 The performance is a lot better for large folios, and the large order allocation failure rate is only very slightly higher or unchanged even for !SWP_SYNCHRONOUS_IO devices high pressure.

mm: change vma_start_read() to drop RCU lock on failure
vma_start_read() can drop and reacquire RCU lock in certain failure cases. It's not apparent that the RCU session started by the caller of this function might be interrupted when vma_start_read() fails to lock the vma. This might become a source of subtle bugs and to prevent that we change the locking rules for vma_start_read() to drop RCU read lock upon failure. This way it's more obvious that RCU-protected objects are unsafe after vma locking fails.

mm: limit the scope of vma_start_read()
Limit the scope of vma_start_read() as it is used only as a helper for higher-level locking functions implemented inside mmap_lock.c and we are about to introduce more complex RCU rules for this function. The change is pure code refactoring and has no functional changes.

zram: protect recomp_algorithm_show() with ->init_lock
sysfs handlers should be called under ->init_lock and are not supposed to unlock it until return, otherwise e.g. a concurrent reset() can occur. There is one handler that breaks that rule: recomp_algorithm_show(). Move ->init_lock handling outside of __comp_algorithm_show() (also drop it and call zcomp_available_show() directly) so that the entire recomp_algorithm_show() loop is protected by the lock, as opposed to protecting individual iterations. The patch does not need to go to -stable, as it does not fix any runtime errors (at least I can't think of any). It makes recomp_algorithm_show() "atomic" w.r.t. zram reset() (just like the rest of zram sysfs show() handlers), that's a pretty minor change.

mm: memory-tiering: fix PGPROMOTE_CANDIDATE counting
Goto-san reported confusing pgpromote statistics where the pgpromote_success count significantly exceeded pgpromote_candidate. On a system with three nodes (nodes 0-1: DRAM 4GB, node 2: NVDIMM 4GB): # Enable demotion only echo 1 > /sys/kernel/mm/numa/demotion_enabled numactl -m 0-1 memhog -r200 3500M >/dev/null & pid=$! sleep 2 numactl memhog -r100 2500M >/dev/null & sleep 10 kill -9 $pid # terminate the 1st memhog # Enable promotion echo 2 > /proc/sys/kernel/numa_balancing After a few seconds, we observeed `pgpromote_candidate < pgpromote_success` $ grep -e pgpromote /proc/vmstat pgpromote_success 2579 pgpromote_candidate 0 In this scenario, after terminating the first memhog, the conditions for pgdat_free_space_enough() are quickly met, and triggers promotion. However, these migrated pages are only counted for in PGPROMOTE_SUCCESS, not in PGPROMOTE_CANDIDATE. To solve these confusing statistics, introduce PGPROMOTE_CANDIDATE_NRL to count the missed promotion pages. And also, not counting these pages into PGPROMOTE_CANDIDATE is to avoid changing the existing algorithm or performance of the promotion rate limit.

mm/mglru: update MG-LRU proactive reclaim statistics only to memcg
Users can use /sys/kernel/debug/lru_gen to trigger proactive memory reclaim of a specified memcg. Currently, statistics such as pgrefill, pgscan and pgsteal will be updated to the /proc/vmstat system memory statistics. This will confuse some system memory pressure monitoring tools, making it difficult to determine whether pgscan and pgsteal are caused by system-level pressure or by proactive memory reclaim of some specific memory cgroup. Therefore, make this interface behave similarly to memory.reclaim. Update proactive memory reclaim statistics only to its memory cgroup.

mempolicy: clarify what zone reclaim means
The zone_reclaim_mode API controls the reclaim behavior when a node runs out of memory. Contrary to its user-facing name, it is internally referred to as "node_reclaim_mode". This can be confusing. But because we cannot change the name of the API since it has been in place since at least 2.6, let's try to be more explicit about what the behavior of this API is. Change the description to clarify what zone reclaim entails, and be explicit about the RECLAIM_ZONE bit, whose purpose has led to some confusion in the past already [1] [2].

mm: fix possible deadlock in kmemleak
There are some AA deadlock issues in kmemleak, similar to the situation
reported by Breno [1]. The deadlock path is as follows:
mem_pool_alloc()
-> raw_spin_lock_irqsave(&kmemleak_lock, flags);
-> pr_warn()
-> netconsole subsystem
-> netpoll
-> __alloc_skb
-> __create_object
-> raw_spin_lock_irqsave(&kmemleak_lock, flags);
To solve this problem, switch to printk_safe mode before printing warning
message, this will redirect all printk()-s to a special per-CPU buffer,
which will be flushed later from a safe context (irq work), and this
deadlock problem can be avoided. The proper API to use should be
printk_deferred_enter()/printk_deferred_exit() [2]. Another way is to
place the warn print after kmemleak is released.

ALSA: usb-audio: Allow Focusrite devices to use low samplerates
Commit 05f254a6369ac020fc0382a7cbd3ef64ad997c92 ("ALSA: usb-audio:
Improve filtering of sample rates on Focusrite devices") changed the
check for max_rate in a way which was overly restrictive, forcing
devices to use very high samplerates if they support them, despite
support existing for lower rates as well.
This maintains the intended outcome (ensuring samplerates selected are
supported) while allowing devices with higher maximum samplerates to be
opened at all supported samplerates.
This patch was tested with a Clarett+ 8Pre USB

kselftest/arm64: Don't open code SVE_PT_SIZE() in fp-ptrace
In fp-trace when allocating a buffer to write SVE register data we open
code the addition of the header size to the VL depeendent register data
size, which lead to an underallocation bug when we cut'n'pasted the code
for FPSIMD format writes. Use the SVE_PT_SIZE() macro that the kernel
UAPI provides for this.

arm64: mm: Fix CFI failure due to kpti_ng_pgd_alloc function signature
Seen during KPTI initialization:
CFI failure at create_kpti_ng_temp_pgd+0x124/0xce8 (target: kpti_ng_pgd_alloc+0x0/0x14; expected type: 0xd61b88b6)
The call site is alloc_init_pud() at arch/arm64/mm/mmu.c:
pud_phys = pgtable_alloc(TABLE_PUD);
alloc_init_pud() has the prototype:
static void alloc_init_pud(p4d_t *p4dp, unsigned long addr, unsigned long end,
phys_addr_t phys, pgprot_t prot,
phys_addr_t (*pgtable_alloc)(enum pgtable_type),
int flags)
where the pgtable_alloc() prototype is declared.
The target (kpti_ng_pgd_alloc) is used in arch/arm64/kernel/cpufeature.c:
create_kpti_ng_temp_pgd(kpti_ng_temp_pgd, __pa(alloc), KPTI_NG_TEMP_VA,
PAGE_SIZE, PAGE_KERNEL, kpti_ng_pgd_alloc, 0);
which is an alias for __create_pgd_mapping_locked() with prototype:
extern __alias(__create_pgd_mapping_locked)
void create_kpti_ng_temp_pgd(pgd_t *pgdir, phys_addr_t phys,
unsigned long virt,
phys_addr_t size, pgprot_t prot,
phys_addr_t (*pgtable_alloc)(enum pgtable_type),
int flags);
__create_pgd_mapping_locked() passes the function pointer down:
__create_pgd_mapping_locked() -> alloc_init_p4d() -> alloc_init_pud()
But the target function (kpti_ng_pgd_alloc) has the wrong signature:
static phys_addr_t __init kpti_ng_pgd_alloc(int shift);
The "int" should be "enum pgtable_type".
To make "enum pgtable_type" available to cpufeature.c, move
enum pgtable_type definition from arch/arm64/mm/mmu.c to
arch/arm64/include/asm/mmu.h.
Adjust kpti_ng_pgd_alloc to use "enum pgtable_type" instead of "int".
The function behavior remains identical (parameter is unused).

ALSA: hda: tas2781: reorder tas2563 calibration variables
The tasdev_load_calibrated_data() function expects the calibration data
values in the cali_data buffer as R0, R0Low, InvR0, Power, TLim which
is not the same as what tas2563_save_calibration() writes to the buffer.
Reorder the EFI variables in the tas2563_save_calibration() function
to put the values in the buffer in the correct order.

ALSA: hda: tas2781: fix tas2563 EFI data endianness
Before conversion to unify the calibration data management, the
tas2563_apply_calib() function performed the big endian conversion and
wrote the calibration data to the device. The writing is now done by the
common tasdev_load_calibrated_data() function, but without conversion.
Put the values into the calibration data buffer with the expected
endianness.

ALSA: firewire-motu: drop EPOLLOUT from poll return values as write is not supported
The ALSA HwDep character device of the firewire-motu driver incorrectly
returns EPOLLOUT in poll(2), even though the driver implements no operation
for write(2). This misleads userspace applications to believe write() is
allowed, potentially resulting in unnecessarily wakeups.
This issue dates back to the driver's initial code added by a commit
71c3797779d3 ("ALSA: firewire-motu: add hwdep interface"), and persisted
when POLLOUT was updated to EPOLLOUT by a commit a9a08845e9ac ('vfs: do
bulk POLL* -> EPOLL* replacement("").').
This commit fixes the bug.

ARM:
- Correctly handle 'invariant' system registers for protected VMs
- Improved handling of VNCR data aborts, including external aborts
- Fixes for handling of FEAT_RAS for NV guests, providing a sane
fault context during SEA injection and preventing the use of
RASv1p1 fault injection hardware
- Ensure that page table destruction when a VM is destroyed gives an
opportunity to reschedule
- Large fix to KVM's infrastructure for managing guest context loaded
on the CPU, addressing issues where the output of AT emulation
doesn't get reflected to the guest
- Fix AT S12 emulation to actually perform stage-2 translation when
necessary
- Avoid attempting vLPI irqbypass when GICv4 has been explicitly
disabled for a VM
- Minor KVM + selftest fixes
RISC-V:
- Fix pte settings within kvm_riscv_gstage_ioremap()
- Fix comments in kvm_riscv_check_vcpu_requests()
- Fix stack overrun when setting vlenb via ONE_REG
x86:
- Use array_index_nospec() to sanitize the target vCPU ID when handling PV
IPIs and yields as the ID is guest-controlled.
- Drop a superfluous cpumask_empty() check when reclaiming SEV memory, as
the common case, by far, is that at least one CPU will have entered the
VM, and wbnoinvd_on_cpus_mask() will naturally handle the rare case where
the set of have_run_cpus is empty.
Selftests (not KVM):
- Rename the is_signed_type() macro in kselftest_harness.h to is_signed_var()
to fix a collision with linux/overflow.h. The collision generates compiler
warnings due to the two macros having different meaning.

hardening: Require clang 20.1.0 for __counted_by
After an innocuous change in -next that modified a structure that
contains __counted_by, clang-19 start crashing when building certain
files in drivers/gpu/drm/xe. When assertions are enabled, the more
descriptive failure is:
clang: clang/lib/AST/RecordLayoutBuilder.cpp:3335: const ASTRecordLayout &clang::ASTContext::getASTRecordLayout(const RecordDecl *) const: Assertion `D && "Cannot get layout of forward declarations!"' failed.
According to a reverse bisect, a tangential change to the LLVM IR
generation phase of clang during the LLVM 20 development cycle [1]
resolves this problem. Bump the version of clang that enables
CONFIG_CC_HAS_COUNTED_BY to 20.1.0 to ensure that this issue cannot be
hit.

allow a user to ignore ports that are advertized as external (hotplug
capable) in favor of lower link power management policies instead of

ASoC: Fixes for v6.17
The main fixes here are for some of the cleanups done in the core in this release, we had broken component lookup in the case with a single bus and DMA controller. Otherwise it's driver specific changes, the shortlogs for the Intel WCL and rsnd drivers look like minor cleanups but are actually bugfixes (adding an op needed for correct functionality and reverting an inappropriate helper usage). -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmixaaEACgkQJNaLcl1U h9DioQf+PKWlxGo/McqedxpEb3LvsOzY0UTgsWLLhNjfghS+9GdSFLtIclG6ekqe Cl3W0z5KJQcmiOyG9Uyr4OwyqfzTgggIhQ1t7ILSuI9Ogm2sQTF4c7UdbhkX6AUz IG841gzLVQA6Lo4qqceoEKvycNVndkGrkGSqEYEvrlhTxjlg1NycWMdiB+Yh6FqK 8/ToiWPbRSYd9WlBttWgc0Luj433ErcNqhTvuXXC0R5milcVA3XpcStgWLfBHTXe qlZrWlTzBaqaT31fpEuFGzbjo1BqXjcqgofcpuyf6xBTjSvFQsqIr17yNHUtxz8P tgkLOs6ffclMviamcCAyLJsGzQ+d5A== =K12t -----END PGP SIGNATURE----- Merge tag 'asoc-fix-v6.17-rc3' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v6.17 The main fixes here are for some of the cleanups done in the core in this release, we had broken component lookup in the case with a single bus and DMA controller.

drm/mediatek: mtk_hdmi: Fix inverted parameters in some regmap_update_bits calls
In mtk_hdmi driver, a recent change replaced custom register access
function calls by regmap ones, but two replacements by regmap_update_bits
were done incorrectly, because original offset and mask parameters were
inverted, so fix them.
