From: Zhang Yi <yi.zhang@xxxxxxxxxx> Hello! This is the e2fsprogs part of the ext4 journal_cycle_record mount option(corresponding kernel part is at [1]). It add a new parameter to record the journal head of a clean filesystem, mke2fs initialize it to the start of journal area, and e2fsck check and fix it if it's bad, and also update it after recovering journal. Basic functional tests have been passed. Thanks, Yi.
