[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.

[PATCH 0/6] Btrfs commit fixes, async subvol operations
Hi Chris,
This is the extent of my current queue of Btrfs snapshot/subvol/commit
stuff. Most of these were posted several months ago. Can be sent
upstream during this merge window? Not having this functionality is
becoming a bit of a roadblock for our efforts to keep the Ceph data in a
consistent state.
These patches are also available from
