Christian Brauner <brauner@kernel.org> says: This converts all users of override_creds() to rely on credentials guards. Leave all those that do the prepare_creds() + modify creds + override_creds() dance alone for now. Some of them qualify for their own variant. * patches from https://patch.msgid.link/20251103-work-creds-guards-simple-v1-0-a3e156839e7f@kernel.org: net/dns_resolver: use credential guards in dns_query() cgroup: use credential guards in cgroup_attach_permissions() act: use credential guards in acct_write_process() smb: use credential guards in cifs_get_spnego_key() nfs: use credential guards in nfs_idmap_get_key() nfs: use credential guards in nfs_local_call_write() nfs: use credential guards in nfs_local_call_read() erofs: use credential guards binfmt_misc: use credential guards backing-file: use credential guards for mmap backing-file: use credential guards for splice write backing-file: use credential guards for splice read backing-file: use credential guards for writes backing-file: use credential guards for reads aio: use credential guards cred: add {scoped_}with_creds() guards Link: https://patch.msgid.link/20251103-work-creds-guards-simple-v1-0-a3e156839e7f@kernel.org Signed-off-by: Christian Brauner <brauner@kernel.org>
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.
