[GIT PULL] Btrfs for 3.16
From: Chris Mason
Date: Wed Jun 11 2014 - 11:59:23 EST
Hi Linus,
Please pull my for-linus branch:
git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus
The biggest change here is Josef's rework of the btrfs quota accounting,
which improves the in-memory tracking of delayed extent operations.
I had been working on Btrfs stack usage for a while, mostly because it
had become impossible to do long stress runs with slab, lockdep and
pagealloc debugging turned on without blowing the stack. Even though
you upgraded us to a nice king sized stack, I kept most of the patches.
We also have some very hard to find corruption fixes, an awesome sysfs
use after free, and the usual assortment of optimizations, cleanups and
other fixes.
