From: Omar Sandoval <osandov@xxxxxx> This is v2 of my earlier series "Btrfs: fix free space tree bitmaps+tests on big-endian systems" [1]. Patches 1, 4, and 5 are the same as patches 1, 2, and 3 from the original series. I've added patch 2 to fix another bug I noticed (an xfstest went out earlier). Patch 3 is the result of the earlier discussion here [2]. Finally, patch 6 was necessary to get the sanity tests to run on my MIPS emulator. This series applies to v4.8-rc7. The sanity tests pass on both x86-64 and MIPS, and there are no xfstests regressions. Chandan and Anatoly, could you test these out as well? I'm working on the btrfs-progs follow up, but these patches are safe without that -- the new FREE_SPACE_TREE_VALID bit will stop all versions of btrfs-progs from mounting read-write.
