Merge tag 'fs.acl.v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/idmapping
Pull vfs acl update from Christian Brauner: "This contains a single update to the internal get acl method and replaces an open-coded cmpxchg() comparison with with try_cmpxchg(). It's clearer and also beneficial on some architectures" * tag 'fs.acl.v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/idmapping: posix_acl: Use try_cmpxchg in get_acl
