Linux kernel source tree
b13cddf633
security_path_* based LSM hooks appear to be generally missing from the sleepable_lsm_hooks list. Initially add a small subset of them to the preexisting sleepable_lsm_hooks list so that sleepable BPF helpers like bpf_d_path() can be used from sleepable BPF LSM based programs. The security_path_* hooks added in this patch are similar to the security_inode_* counterparts that already exist in the sleepable_lsm_hooks list, and are called in roughly similar points and contexts. Presumably, making them OK to be also annotated as sleepable. Building a kernel with DEBUG_ATOMIC_SLEEP options enabled and running reasonable workloads stimulating activity that would be intercepted by such security hooks didn't show any splats. Notably, I haven't added all the security_path_* LSM hooks that are available as I don't need them at this point in time.

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 Restructured Text 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.
