Hi everyone,
Our set of btrfs features, fixes and cleanups are in my for-linus
branch:
git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus
There is a conflict in fs/btrfs/extent-tree.c, which I merged here:
git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus-merged
The merge is basically combining da633a42170165cbf20a2d3886c7480ccc832ec3 from
my tree with the new writeback_inodes_sb function from the writeback
tree.
The biggest feature in the pull is the new (and still experimental)
raid56 code that David Woodhouse started long ago. I'm still working
on the parity logging setup that will avoid inconsistent parity after a
crash, so this is only for testing right now. But, I'd really like to
get it out to a broader audience to hammer out any performance issues or
other problems.
scrub does not yet correct errors on raid5/6 either.
Josef has another pass at fsync performance. The big change here is to
combine waiting for metadata with waiting for data, which is a big
latency win. It is also step one toward using atomics from the hardware
during a commit.
Mark Fasheh has a new way to use btrfs send/receive to send only the
metadata changes. SUSE is using this to make snapper more efficient at
finding changes between snapshosts.
Otherwise we have a large number of fixes and cleanups. Eric Sandeen
wins the award for removing the most lines, and I'm hoping we steal this
idea from XFS over and over again.

To people who cares about snapshot-aware defrag, this feature is also included
in the pull.

I *really* wish that big pull requests like this would come in earlier
in the merge window. I hate seeing them the day before I close the
window - really. A number of the latter commits are done in the last
few days, which also smells bad.

Definitely, I wanted to send this earlier in the merge window. But I
was out last week and also didn't want to send the big stuff (raid 5/6
and the fsync work) to you right before I left on vacation.
So instead I sent things off to linux-next, and everyone on the btrfs
list collected fixes while I was gone.
