[PATCH v2 0/3] btrfs: small changes to "usebackuproot" mount

[CHANGELOG]
v2:
- Also include "rescue=usebackroot" into "rescue=all" shortcut

"rescue=usebackuproot" mount option is not requiring a read-only mount,
which is different from all the other options in the "rescue=" group.
Address that in the first patch.

Standalone "usebackuproot" mount option is already marked deprecated
since v5.9, I see no practical reason to keep supporting it in 2026.
Just remove it in the second patch.


Qu Wenruo (3):
  btrfs: add "rescue=usebackuproot" into forced read-only options
  btrfs: add "rescue=usebackuproot" into "rescue=all" shortcut
  btrfs: remove "usebackuproot" mount option
