Hello Lee, I'm using this functionality all the time to test how SCSI target code handles TMFs while SCSI commands are in progress. So I would regret if the SCSI reset ioctl code would be modified such that it waits for outstanding requests. Isn't the behavior you described a SCSI LLD bug? Shouldn't such bugs be fixed instead of implementing a work-around in the SCSI core? Thanks, Bart.
