[PATCH V7 0/3][PULL REQUEST] Unify 'norecovery' bahavior with other filesystems

[Qu Wenruo <quwenruo@cn.fujitsu.com>]

'Norecovery' mount option is almost a standard for all other
filesystems, including f2fs, ext4, gfs2, nilfs2, and xfs.
And since current 'recovery' mount option for btrfs is too generic, it's
better to change btrfs 'recovery' to 'usebackuproot' and then we can
safely add 'norecovery' and 'nologreplay' mount option for btrfs.

The patch itself is not huge and already tested by others since v2.
Only mount option name and patch slipting is changing during all
these version changes.

Qu Wenruo (3):
  btrfs: Introduce new mount option usebackuproot to replace recovery
  btrfs: Introduce new mount option to disable tree log replay
  btrfs: Introduce new mount option alias for nologreplay
