From: Zhang Yi <yi.zhang@xxxxxxxxxxxxxxx> v1->v2: - Fix the format type warning. - Add more check of journal_cycle_record mount options in remount. Hello, This patch set introduce a new mount option names journal_cycle_record, it save journal head for a clean unmounted file system, let ext4 continue/cycled record new journal transactions after previous mount or recovered transactions for unclean file system. It could give us more info when analysing a corrupted file system image and locate kernel consistency bugs more conveniently. This is just the kernel part and have already passed throuth xfstests in auto mode (it depends on one prefix patch[1]). I will continue the e2fsprogs' part if nobody strong dislike that. Any comments are welcome. [1] https://lore.kernel.org/linux-ext4/20230130111138.76tp6pij3yhh4brh@quack3/T/#m96a1cffd567bdd844233b3115a6635391ed0b45b Thanks, Yi.
