Hi Linus,
Could you pull these fixes for FS-Cache and Cachefiles:
(1) Put a timeout in releasepage() to deal with a recursive hang between the
memory allocator, writeback, ext4 and fscache under memory pressure.
(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
