4Subject: [PATCH] e2fsck: exit journal recovery when find EIO, ENOMEM
5 errors
6
7jbd2_journal_revocer() may fail when some error occers
8such as ENOMEM. However, jsb->s_start is still cleared
9by func e2fsck_journal_release(). This may break
10consistency between metadata and data in disk. Sometimes,
11failure in jbd2_journal_revocer() is temporary but retry
12e2fsck will skip the journal recovery when the temporary
13problem is fixed.
14
15To fix this case, we use "fatal_error" instead "goto errout"
16when recover journal failed. If journal recovery fails, we
17will send error message to user and reserve the recovery
18flags to recover the journal when try e2fsck again.
