I'm still not entirely happy with this. You keep making the tty a special case by removing it from the files per-sb files list while nothing else in the system is removed from it. Thinks would be much better if you could untangle the tty code from abuse of file->f_u.fu_list entirely. And from a naive look at the tty code that actually seems pretty easy. file->private for ttys currently directly points to the tty struct. If you add a tty_private there which points back to the file, the tty and contains a list_head the open files in tty code tracking code can be completely divorced from the per-sb file tracking. After that we can decide what to do with the per-sb file tracking, where my favourite still is to get rid of it entirely. -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
