Subject: [PATCH 00/11] rbd bug fix and discard support
Date: Tue, 8 Apr 2014 13:42:44 -0700 [thread overview]
Message-ID: <cover.1396987789.git.josh.durgin@inktank.com> (raw)
The first patch in this series fixes a potential race, which may have
been related to http://tracker.ceph.com/issues/7465, though there's
not enough information to tell. I put it before the discard-related
patches so it could be cherry-picked to older kernels as needed.
The next three patches are rebased versions of Guangliang's discard
patches, which have already been reviewd.
The rest are bug fixes which made discard work in my testing for
format 1 and layered format 2 images.
Guangliang Zhao (3):
rbd: skip the copyup when an entire object writing
rbd: extend the operation type
rbd: add discard support for rbd
Josh Durgin (8):
rbd: access snapshot context and mapping size safely
rbd: read image size for discard check safely
rbd: fix snapshot context reference count for discards
rbd: tolerate -ENOENT for discard operations
rbd: make discard trigger copy-on-write
rbd: extract a method for adding object operations
rbd: use helpers to handle discard for layered images correctly
rbd: set the remaining discard properties to enable support
