Pull apparmor updates from John Johansen:
 "Features:
   - switch to zstd compression for profile raw data

  Cleanups:
   - simplify obtaining the newest label on a cred
   - remove useless static inline functions
   - compute permission conversion on policy unpack
   - refactor code to share common permissins
   - refactor unpack to group policy backwards compatiblity code
   - add __init annotation to aa_{setup/teardown}_dfa_engine()

  Bug Fixes:
   - fix a memleak in
       - multi_transaction_new()
       - free_ruleset()
       - unpack_profile()
       - alloc_ns()
   - fix lockdep warning when removing a namespace
   - fix regression in stacking due to label flags
   - fix loading of child before parent
   - fix kernel-doc comments that differ from fns
   - fix spelling errors in comments
   - store return value of unpack_perms_table() to signed variable"
