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.
