Subject: [GIT PULL] Btrfs
Hi Linus,
I waited an extra day to send this one out because I hit a crash late
last week with CONFIG_DEBUG_PAGEALLOC enabled (fixed in the top commit).
Please pull my my for-linus-4.6 branch:
git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus-4.6
We have a good sized cleanup of our internal read ahead code, and the
first series of commits from Chandan to enable PAGE_SIZE > sectorsize
Otherwise, it's a normal series of cleanups and fixes, with many thanks
to Dave Sterba for doing most of the patch wrangling this time.
