Subject: [GIT PULL] Btrfs updates
Hi Linus,
Please pull my for-linus branch:
git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus
Miao Xie has been very busy, fixing races and enospc problems and many
other small but important pieces.
Alexandre Oliva discovered some problems with how our error handling was
interacting with the block layer and for now has disabled our partial
handling of sub-page writes. The real sub-page work is in a series of
patches from IBM that we still need to integrate and test. The code
Alexandre has turned off was really incomplete.
Josef has more error handling fixes and an important fix for the new
skinny extent format.
This also has my fix for the tracepoint crash from late in 3.9. It's
the first stage in a larger clean up to get rid of btrfs_bio and make
a proper bioset for all the items we need to tack into the bio. For now
the bioset only holds our mirror_num and stripe_index, but for the next
merge window I'll shuffle more in.
