Hi all, I've received reports claiming they're seeing a double command completion occasionally when a command timeout happens. Delving into it I found this this indeed might happening; reason being that the LLDD will only be informed about a timed-out command by calling scsi_try_to_abort_command(). Anytime before that the LLDD is free to assume the command is valid and might call scsi_done() on it. Which then will lead to interesting issues in the error handler. And while debugging this I've found we're setting DID_TIME_OUT incorrectly, which might lead to spurious command timeout detection.
