Subject: [PATCH 0/4] e2fsprogs: journal cycled record transactions between each mount

From: Zhang Yi <yi.zhang@...wei.com>

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.
