Merge tag 'lsm-pr-20260615' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm

Pull lsm update from Paul Moore:
 "A single LSM update the security_inode_listsecurity() hook to be able
  to leverage the xattr_list_one() helper function.

  We wanted to do this for a while, but we needed to fixup the callers
  in the NFS code first. With the NFS code changes shipping in Linux
  v7.0 and no one complaining, it seemed a good time to complete the
  shift"
