[f2fs-dev] [PATCH] fsck.f2fs: fix checking wp of all devices

[Sheng Yong via Linux-f2fs-devel]

For zoned model, the first device (devices[0]) is not zoned device,
whose zoned_model is not F2FS_ZONED_HM. Let's skip it and check write
pointer of left devices continuously.

[f2fs-dev] [PATCH] fsck.f2fs: update superblock if invalid

[Sheng Yong via Linux-f2fs-devel]

If a superblock failed in sanity check, it should be fixed. This patch
add a new state `sb_invalid' to tell fsck needs to update superblock
at the end of all checkings.

This patch also cleans up force_stop, abnormal_stop, fs_errors and
sb_invalid by merging them into an `invalid_sb' flags, and each of
them is indicated using one bit.
