Five fixes addressing PREEMPT_RT compatibility and locking issues. Three commits fix potential deadlocks and sleeps in atomic contexts on RT kernels by converting locks to raw spinlocks and ensuring IRQ work runs in hard-irq context. The remaining two fix unsafe locking in the debug dump path and a variable dereference typo. -----BEGIN PGP SIGNATURE----- iIQEABYKACwWIQTfIjM1kS57o3GsC/uxYfJx3gVYGQUCaRs/0w4cdGpAa2VybmVs Lm9yZwAKCRCxYfJx3gVYGRjVAQClymu/aOROE97FWD+JEsuNYIse5qkBEiAfJtWR D9pz7QD+IGyvvF51zVS1tM8eBVoO0AX2Xc6vY/rfY9p9RUfRKwo= =OwLv -----END PGP SIGNATURE----- Merge tag 'sched_ext-for-6.18-rc6-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext Pull sched_ext fixes from Tejun Heo: "Five fixes addressing PREEMPT_RT compatibility and locking issues.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
