Pull fscache and cachefiles fixes from David Howells: "Misc fixes: - Fix an assertion failure at fs/cachefiles/xattr.c:138 caused by a race between a cache object lookup failing and someone attempting to reenable that object, thereby triggering an update of the object's attributes. - Fix an assertion failure at fs/fscache/operation.c:449 caused by a split atomic subtract and atomic read that allows a race to happen. - Fix a leak of backing pages when simultaneously reading the same page from the same object from two or more threads. - Fix a hang due to a race between a cache object being discarded and the corresponding cookie being reenabled. There are also some minor cleanups: - Cast an enum value to a different enum type to prevent clang from generating a warning. This shouldn't cause any sort of change in the emitted code. - Use ktime_get_real_seconds() instead of get_seconds(). This is just used to uniquify a filename for an object to be placed in the graveyard. Objects placed there are deleted by cachfilesd in userspace immediately thereafter. - Remove an initialised, but otherwise unused variable. This should have been entirely optimised away anyway" * tag 'fscache-fixes-20181130' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs: fscache, cachefiles: remove redundant variable 'cache' cachefiles: avoid deprecated get_seconds() cachefiles: Explicitly cast enumerated type in put_object fscache: fix race between enablement and dropping of object cachefiles: Fix page leak in cachefiles_read_backing_file while vmscan is active fscache: Fix race in fscache_op_complete() due to split atomic_sub & read cachefiles: Fix an assertion failure when trying to update a failed object
