i've double-checked that there are no other video drivers affected by this problem:
$ cd drivers/media/ $ grep -C 10 videobuf_mmap_setup `grep -l mutex_lock */*.c */*/*.c */*/*/*.c`
video/videobuf-core.c- mutex_lock(&q->lock); video/videobuf-core.c- mutex_lock(&q->lock); video/bt8xx/bttv-driver.c- mutex_lock(&fh->cap.lock);
so only bttv-driver.c was affected, at first sight.
