Public bug reported:
One of the threads in gnome-settings-deamon is polling every 4 seconds
trying to add a watch onto a non-existent directory /usr/X11R6/lib/X11:
inotify_add_watch(16, "/usr/X11R6/lib/X11",
IN_MODIFY|IN_ATTRIB|IN_CLOSE_WRITE|IN_MOVED_FROM|IN_MOVED_TO|IN_CREATE|IN_DELETE|IN_DELETE_SELF|IN_MOVE_SELF|IN_UNMOUNT|IN_ONLYDIR)
= -1 ENOENT (No such file or directory)
poll([{fd=17, events=POLLIN}, {fd=16, events=POLLIN}], 2, 3999) = 0 (Timeout)
inotify_add_watch(16, "/usr/X11R6/lib/X11",
IN_MODIFY|IN_ATTRIB|IN_CLOSE_WRITE|IN_MOVED_FROM|IN_MOVED_TO|IN_CREATE|IN_DELETE|IN_DELETE_SELF|IN_MOVE_SELF|IN_UNMOUNT|IN_ONLYDIR)
= -1 ENOENT (No such file or directory)
poll([{fd=17, events=POLLIN}, {fd=16, events=POLLIN}], 2, 3996) = 0 (Timeout)
inotify_add_watch(16, "/usr/X11R6/lib/X11",
IN_MODIFY|IN_ATTRIB|IN_CLOSE_WRITE|IN_MOVED_FROM|IN_MOVED_TO|IN_CREATE|IN_DELETE|IN_DELETE_SELF|IN_MOVE_SELF|IN_UNMOUNT|IN_ONLYDIR)
= -1 ENOENT (No such file or directory)
poll([{fd=17, events=POLLIN}, {fd=16, events=POLLIN}], 2, 3999) = 0 (Timeout)
inotify_add_watch(16, "/usr/X11R6/lib/X11",
IN_MODIFY|IN_ATTRIB|IN_CLOSE_WRITE|IN_MOVED_FROM|IN_MOVED_TO|IN_CREATE|IN_DELETE|IN_DELETE_SELF|IN_MOVE_SELF|IN_UNMOUNT|IN_ONLYDIR)
= -1 ENOENT (No such file or directory)
poll([{fd=17, events=POLLIN}, {fd=16, events=POLLIN}], 2, 3996) = 0 (Timeout)
inotify_add_watch(16, "/usr/X11R6/lib/X11",
IN_MODIFY|IN_ATTRIB|IN_CLOSE_WRITE|IN_MOVED_FROM|IN_MOVED_TO|IN_CREATE|IN_DELETE|IN_DELETE_SELF|IN_MOVE_SELF|IN_UNMOUNT|IN_ONLYDIR)
= -1 ENOENT (No such file or directory)
poll([{fd=17, events=POLLIN}, {fd=16, events=POLLIN}], 2, 3998) = 0 (Timeout)
inotify_add_watch(16, "/usr/X11R6/lib/X11",
IN_MODIFY|IN_ATTRIB|IN_CLOSE_WRITE|IN_MOVED_FROM|IN_MOVED_TO|IN_CREATE|IN_DELETE|IN_DELETE_SELF|IN_MOVE_SELF|IN_UNMOUNT|IN_ONLYDIR)
= -1 ENOENT (No such file or directory)
is that intentional, or a bug? As it stands, it's causing some wakeups
that seem unnecessary and this is keeping the system from deep C state
idle, which is wasting power.
