Merge tag 'lsm-pr-20231030' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm

Pull LSM updates from Paul Moore:

 - Add new credential functions, get_cred_many() and put_cred_many() to
   save some atomic_t operations for a few operations.

   While not strictly LSM related, this patchset had been rotting on the
   mailing lists for some time and since the LSMs do care a lot about
   credentials I thought it reasonable to give this patch a home.

 - Five patches to constify different LSM hook parameters.

 - Fix a spelling mistake.
