I'm runnning 2.6.36-rc1, with CONFIG_FANOTIFY and 
CONFIG_FANOTIFY_ACCESS_PERMISSIONS on apparently.  I am watching the same 
directory with inotify and fanotify at the same time, that is, with both an 
inotify and an fanotify listener running in two separate processes.  The 
inotify listener is code I cannot send so easily, but I've shown the resulting 
strace.  The fanotify listener is the one from [1].

	[1] http://git.kernel.org/?p=linux/kernel/git/agruen/fanotify-example.git

Together with the traces I've provided this should give you way enough clues 
to be able to look up in the code why listening for fanotify events apparently 
causes a concurrent inotify listener to return an inotify event with struct 
inotify_event->mask == 0 for each fanotify perm event.
