fsck.ubifs: Replay journal
This is the 2/18 step of fsck. Replay journal, update TNC & LPT.
There could be following steps and possible errors:
Step 1. scan log LEB, get all bud LEBs
a. corrupted scanning data in log area: danger mode with rebuild_fs and
normal mode with 'yes' answer will turn to rebuild filesystem, other
modes will exit.
Step 2. scan bud LEBs, get all nodes
a. corrupted scanning data in bud LEB: danger mode and normal mode with
'yes' answer will drop bud LEB and set %FR_LPT_INCORRECT for lpt
status, other modes will exit.
Step 3. apply nodes, record latest isize into size_tree
Step 4. apply nodes, update TNC & LPT
a. corrupted data searched from TNC: skip node and set %FR_LPT_INCORRECT
lpt status for danger mode and normal mode with 'yes' answer, other
modes will exit.
b. corrupted index node read from TNC: danger mode with rebuild_fs and
normal mode with 'yes' answer will turn to rebuild filesystem, other
modes will exit.
c. corrupted lpt: Set %FR_LPT_CORRUPTED for lpt status. Ignore the
error.
d. incorrect lpt: Set %FR_LPT_INCORRECT for lpt status. Ignore the
error.
e. If lpt status is not empty, skip updating lpt.
