[Linux-cachefs] [PATCH 0/8] ceph: fscache support & upstream changes

[Milosz Tanski]

Hey gang I think this should be final revision of these changes. The changes 
are:

 * David rewrote the cookie validity check (that originally was written by
   Hongyi Jia). You might have seen some emails flying about doing it the
   right way.
 * I added crash fix when for Ceph filesystems mounted with nofsc (default)
   when fscache is compiled into Ceph. Previously it would crash trying to
   enqueue invalidate checks in the work queue because we didn't initialize
   if the mount had fscache disabled.

I've tested both changes on my cluster. You can get get these changes from my
branch in bitbucket. It contains the upstream wip-fscache branch rebased with
David's rewrite of Hongyi Jia's changes.

The branch is located at.

  https://bitbucket.org/adfin/linux-fs.git in the wip-fscahce branch

Finally, David requested that this patchset go through the Ceph tree. The tree
should have all the proper sign off from David. I also CC'ed him so he can give
his final okay.

Best,
 - Milosz
