Yes, the kernel behavior looks like a inotify bug which should be fixed.
Hmm, I can't reproduce the inotify issue in a test program. It must be some weird combination of things udev is doing, which triggers this. Anyway, I'm pretty confident, that this is all fixed now and should not happen anymore. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
