[Chris Mason]

Hi Linus,

My for-linus-4.9 branch:

git://git.kernel.org/pub/scm/linux/kernel/git/mason/linux-btrfs.git for-linus-4.9

This isn't heavily used yet, but as we move toward making it the new
default we wanted to nail down an endian bug.

    Btrfs: expand free space tree sanity tests to catch endianness bug (+96/-68)
    Btrfs: fix extent buffer bitmap tests on big-endian systems (+51/-36)
    Btrfs: fix free space tree bitmaps on big-endian systems (+76/-27)
    Btrfs: fix mount -o clear_cache,space_cache=v2 (+12/-12)
    Btrfs: catch invalid free space trees (+24/-2)

David Sterba (2) commits (+13/-12):
    btrfs: tests: uninline member definitions in free_space_extent (+2/-1)
