(2) Fix a pair of refcount bugs in the fscache error handling. (3) Remove a couple of unused pagevecs. This could be punted to -next if you'd rather. (4) 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). I've fixed a bug in "FS-Cache: refcount becomes corrupt under vma pressure." whereby fscache_unuse_cookie() was being passed a cookie rather than an object pointing to that cookie. Thanks, David --- The following changes since commit 68e370289c29e3beac99d59c6d840d470af9dfcf: Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux (2014-08-26 13:50:23 -0700) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs.git tags/fscache-fixes-20140917 for you to fetch changes up to e2cf1f1cc7636bd860e47cd0ad6194da8975f8b5: CacheFiles: Handle rename2 (2014-09-17 23:29:53 +0100) ---------------------------------------------------------------- FS-Cache fixes ---------------------------------------------------------------- David Howells (1): CacheFiles: Handle rename2 Milosz Tanski (3): FS-Cache: Timeout for releasepage() FS-Cache: Reduce cookie ref count if submit fails.
