Andrew, This patch does the following : -Explicit max_per_group authorized for block, fragments, inodes -Remove groupmax recalculations -When mounting ext2 or ^has_journal , we know filesystem is extX relevant. btw, I see a FIXME in journal_update for new journal creation.Does it mean we should patch to have e.g. journalupdate= or that note is obsolete ?
