[PATCH 0/5] asynchronous commit, snapshot ponies
Hi everyone,
This patchset is the latest approach I''m using for the Ceph storage daemon to
keep track of which data has safely committed to disk. The basic idea is to
not use the (problematic) user transaction ioctls at all. Instead, the daemon
quiesces its own write requests, initiates an async snapshot, and then
continues.
The snapshot approach is nice because it provides rollback.
