Hi,

Any chance to get these in this round?  I think they're good fixes,
a memory leak and a warning fix, both are got from xfstests.

- Btrfs: use right range to find checksum for compressed extents
  https://patchwork.kernel.org/patch/1937031/
- Btrfs: fix memory leak on extent map after fsync
  https://patchwork.kernel.org/patch/1946561/

thanks,
liubo
