Hello John McCutchan and Robert Love,
I have a question about inotify_ioctl().
I am investigating if a user process misses the inotify event or gets
wrong event by ioctl(fd, FIONREAD, &pending) in linux-2.6.27, and found
it doesn't acquire dev->ev_mutex lock before accessing dev->queue_size.
In SMP system, is it safe and sure too?
Is the mutex lock unnecessary?
