  Btrfs: use __u64 types in ioctl.h
  Btrfs: fix search_ioctl key advance
  Btrfs: fix gfp flags masking in the compression code
  Btrfs: don't look at bio flags after submit_bio
  btrfs: using btrfs_stack_device_id() get devid
  btrfs: use memparse
  Btrfs: add a "df" ioctl for btrfs
  Btrfs: cache the extent state everywhere we possibly can V2
  Btrfs: cache ordered extent when completing io
  Btrfs: cache extent state in find_delalloc_range
  Btrfs: change the ordered tree to use a spinlock instead of a mutex
  Btrfs: finish read pages in the order they are submitted
  btrfs: fix btrfs_mkdir goto for no free objectids
  Btrfs: flush data on snapshot creation
  Btrfs: make df be a little bit more understandable
