7 days	fsck.ubifs: Replay journal	Zhihao Cheng
	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.

7 days	fsck.ubifs: Read master node & init lpt	Zhihao Cheng
	This is the 1/18 step of fsck. Read and check master node, init lpt. There could be following errors: 1. corrupted scanning data in master area or invalid master node: danger mode with rebuild_fs and normal mode with 'yes' answer will turn to rebuild filesystem, other modes will exit. 2. incorrect space statistics in master node: Set %FR_LPT_INCORRECT for for lpt status. Ignore the error. 3. corrupted lpt: Set %FR_LPT_CORRUPTED for lpt status. Ignore the error.

7 days	fsck.ubifs: Load filesystem information from UBI volume	Zhihao Cheng
	Load filesystem information from UBI volume (Similar to UBIFS mounting process), initialize kinds of buffers and read superblock. This is the base step for both fsck and rebuild_fs. Subsequent pacthes will complete this step by adding more steps(eg. read master, replay journal, etc.) which are only used in fsck.
