[PATCH] inotify: fix race between the kernel and user space
When you rm a watch, an IN_IGNORED event is sent down the event queue
with the watch descriptor that you just rm'd.
If you then add a watch you could get the ignored watch's wd and if you
haven't read the entire event queue, user space will think that it's
newly created watch was just ignored.
To avoid this problem we just use idr_get_new_above instead of
idr_get_new.
