X-Git-Tag: v1.44.3-rc1~58

debugfs: allow read-write opening in catastrophic mode

Allow filesystem to be open read-write in catastrophic mode so that one
can fixup e.g. superblock breakage. The CHECK_FS_BITMAPS flag to
common_args_process() still guards us from doing operations on bitmaps
which we don't load in this mode.
