fs/sysv: stop using write_super and s_dirt
It does not look like sysv FS needs 'write_super()' at all, because all it does is a timestamp update. I cannot test this patch, because this file-system is so old and probably has not been used by anyone for years, so there are no tools to create it in Linux. But from the code I see that marking the superblock as dirty is basically marking the superblock buffers as drity and then setting the s_dirt flag. And when 'write_super()' is executed to handle the s_dirt flag, we just update the timestamp and again mark the superblock buffer as dirty. Seems pointless. It looks like we can update the timestamp more opprtunistically - on unmount or remount of sync, and nothing should change. Thus, this patch removes 'sysv_write_super()' and 's_dirt'.
