Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
Pull btrfs updates from Chris Mason:
"This includes a fairly large change from Josef around data writeback
completion. Before, the writeback wasn't completed until the metadata
insertions for the extent were done, and this made for fairly large
latency spikes on the last page of each ordered extent.
We already had a separate mechanism for tracking pending metadata
insertions, so Josef just needed to tweak things a little to end
writeback earlier on the page. Overall it makes us much friendly to
memory reclaim and lowers latencies quite a lot for synchronous IO.
Jan Schmidt has finished some background work required to track btree
blocks as they go through changes in ownership. It's the missing
piece he needed for both btrfs send/receive and subvolume quotas.
Neither of those are ready yet, but the new tracking code is included
here. Most of the time, the new code is off. It is only used by
scrub and other backref walkers.
Stefan Behrens has added io failure tracking. This includes counters
for which drives are causing the most trouble so the admin (or an
automated tool) can choose to kick them out. We're tracking IO
errors, crc errors, and generation checks we do on each metadata
block.
RAID5/6 did miss the cut this time because I'm having trouble with
corruptions. I'll nail it down next week and post as a beta testing
before 3.6"
