Merge tag 'lsm-pr-20260814' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm

Pull LSM updates from Paul Moore:

 - Remove task_euid()

   The task_euid(), and Rust counterpart, was never widely used, for
   good reason, and now that the only user is gone we're removing it to
   rid ourselves of both dead and funky code.

 - Documentation improvements

   Correct some of the kdoc comments for security_task_prctl() and
   clarify the rust comments on task UID accessors.

 - Fix a memory leak in the LSM syscall selftests
