Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs
Pull btrfs fixes from Chris Mason:
"We've got more bug fixes in my for-linus branch:
One of these fixes another corner of the compression oops from last
time. Miao nailed down some problems with concurrent snapshot
deletion and drive balancing.
I kept out one of his patches for more testing, but these are all
stable"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs:
Btrfs: fix oops caused by the space balance and dead roots
Btrfs: insert orphan roots into fs radix tree
Btrfs: limit delalloc pages outside of find_delalloc_range
Btrfs: use right root when checking for hash collision
