Barnabás Pőcze 3bbccccd05 spa: v4l2: use a separate watch for each device ... Instead of watching /dev, use a separate watch for each device. This is supposed to achieve the same result as the now reverted 88f0dbd6fc ("v4l2: don't set inotify on /dev"): Doing inotify on /dev is not a good idea because we will be woken up by a lot of unrelated events. There is a report of a performance regression on some IO benchmark because of lock contention within the fsnotify subsystem due to this. Instead, just watch for attribute changes on the /dev/videoX files directly. We are only interested in attribute changes, udev should notify us when the file is added or removed.
