You need to queue the rest of the transfer too.
I wrote the original code for this in wfd, and it requeues the transfer for just this reason; the layer above doesn't retry the block operation for the remaining residual. I'm not sure this is an error; it's too long since I looked at the code, but I think there are some bad things that can happen (or were suggested might happen) if you persist in retrying the physical I/O. -- \\ The mind's the standard \\ Mike Smith \\ of the man. \\ msm...@freebsd.org \\ -- Joseph Merrick \\ msm...@cdrom.com To Unsubscribe: send mail to majord...@freebsd.org with "unsubscribe freebsd-current" in the body of the message
