    [PATCH] Alternative tty fasync fix · 0895269a
    Russell King authored
    Instead of detecting when filp->private_data becomes NULL in
    do_tty_hangup and check_tty_count, we remove the file descriptor
    from the list of descriptors associated with the tty.  We use the
    same method that dentry_open() uses.
    
    (It also cleans that up to use a "file_kill()" instead of using a dummy
    "kill_list()" that leaves pointers to stale stack entries that are never
    used)
    
    In addition, we change the for() loops into real list_for_each()
    or list_for_each_entry loops as appropriate.
