- check each file descriptor's open access mode (filp_mode); - treat an error returned by a character driver as a select error; - check all filps in each set before finishing select; - do not copy back file descriptor sets if an error occurred; - remove the hardcoded list of supported character major devices, since all drivers should now be capable of responding properly; - add tests to test40 and fix its error count aggregation.
