Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
Pull btrfs update from Chris Mason:
"These are mostly fixes. The biggest exceptions are Josef's skinny
extents and Jan Schmidt's code to rebuild our quota indexes if they
get out of sync (or you enable quotas on an existing filesystem).
The skinny extents are off by default because they are a new variation
on the extent allocation tree format. btrfstune -x enables them, and
the new format makes the extent allocation tree about 30% smaller.
I rebased this a few days ago to rework Dave Sterba's crc checks on
the super block, but almost all of these go back to rc6, since I
though 3.9 was due any minute.
The biggest missing fix is the tracepoint bug that was hit late in
3.9. I ran into problems with that in overnight testing and I'm still
tracking it down. I'll definitely have that fixed for rc2."
