Subject: [GIT PULL] Btrfs pull -- part 1
Hi Linus,
We still have some corruption fixes and other patches coming in for the
merge window, but this batch is tested and ready to go.
Please pull from:
git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git master
This is a pretty long stream of bug fixes and performance fixes.
Qu Wenruo has replaced the btrfs async threads with regular kernel
workqueues. We'll keep an eye out for performance differences, but it's
nice to be using more generic code for this.
