Subject: [GIT PULL] Btrfs for 4.1
Hi Linus,
Please pull:
git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus-4.1
I've been running these through a longer set of load tests because my
commits change the free space cache writeout. It fixes commit
stalls on large filesystems (~20T space used and up) that we have been
triggering here. We were seeing new writers blocked for 10 seconds or
more during commits, which is far from good.
Josef and I fixed up ENOSPC aborts when deleting huge files (3T or
more), that are triggered because our metadata reservations were not
properly accounting for crcs and were not replenishing during the
truncate.
Also in this series, a number of qgroup fixes from Fujitsu and Dave
Sterba collected most of the pending cleanups from the list.
