Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
Pull btrfs fixes from Chris Mason:
"This has our collection of bug fixes. I missed the last rc because I
thought our patches were making NFS crash during my xfs test runs.
Turns out it was an NFS client bug fixed by someone else while I tried
to bisect it.
All of these fixes are small, but some are fairly high impact. The
biggest are fixes for our mount -o remount handling, a deadlock due to
GFP_KERNEL allocations in readdir, and a RAID10 error handling bug.
This was tested against both 3.3 and Linus' master as of this morning."
