I am interested in why count != max when in user-space number_of_events == t->poll_count - I don't see how that's logically possible, though it makes me wonder why the check is_complete() was put in place - you must have seen this yourself ? As a fundamental though - unless count == max, the test is not done. _______________________________________________ devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxx http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
