Merge branch 'stable-4.10' of git://git.infradead.org/users/pcmoore/audit
Pull audit fixes from Paul Moore: "Two small fixes relating to audit's use of fsnotify. The first patch plugs a leak and the second fixes some lock shenanigans. The patches are small and I banged on this for an afternoon with our testsuite and didn't see anything odd" * 'stable-4.10' of git://git.infradead.org/users/pcmoore/audit: audit: Fix sleep in atomic fsnotify: Remove fsnotify_duplicate_mark()
