#     
#     Pull apparmor updates from John Johansen:
#      "This adds initial support for mediating io_uring and userns creation.
#       Adds a new restriction that tightens the use of change_profile, and a
#       couple of optimizations to reduce performance bottle necks that have
#       been found when retrieving the current task's secid and allocating
#       work buffers.
#     
#       The majority of the patch set continues cleaning up and simplifying
#       the code (fixing comments, removing now dead functions, and macros
#       etc). Finally there are 4 bug fixes, with the regression fix having
#       had a couple months of testing.
#     
#       Features:
#        - optimize retrieving current task secid
#        - add base io_uring mediation
#        - add base userns mediation
#        - improve buffer allocation
#        - allow restricting unprivilege change_profile
#     
#       Cleanups:
#        - Fix kernel doc comments
#        - remove unused declarations
#        - remove unused functions
#        - remove unneeded #ifdef
#        - remove unused macros
#        - mark fns static
#        - cleanup fn with unused return values
#        - cleanup audit data
#        - pass cred through to audit data
#        - refcount the pdb instead of using duplicates
#        - make SK_CTX macro an inline fn
#        - some comment cleanups
#     
#       Bug fixes:
#        - fix regression in mount mediation
#        - fix invalid refenece
#        - use passed in gfp flags
#        - advertise avaiability of extended perms and disconnected.path"
