The only reason to call ext4_commit_super() is to persistent the changed INCOMPAT_RECOVER flag --- well, and to update the global free inode/block counts. OTOH, if the journal_flush() has failed, the fact that the global free counts aren't up to date will be the least of your problems as far as the consistency of the file system snapshot is concerned.... - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
