Subject: [PATCH 0/8] ceph: fscache support & upstream changes
Date: Thu, 5 Sep 2013 18:20:28 -0400 [thread overview]
Message-ID: <cover.1378418255.git.milosz@adfin.com> (raw)
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
