Merge tag 'fscache-fixes-20140917' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
Pull fs-cache fixes from David Howells:
- Put a timeout in releasepage() to deal with a recursive hang between
the memory allocator, writeback, ext4 and fscache under memory
pressure.
- Fix a pair of refcount bugs in the fscache error handling.
- Remove a couple of unused pagevecs.
- The cachefiles requirement that the base directory support rename
should permit rename2 as an alternative - otherwise certain
filesystems cannot now be used as backing stores (such as ext4).
* tag 'fscache-fixes-20140917' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs:
CacheFiles: Handle rename2
cachefiles: remove two unused pagevecs.
FS-Cache: refcount becomes corrupt under vma pressure.
FS-Cache: Reduce cookie ref count if submit fails.
FS-Cache: Timeout for releasepage()
