You were copied on the submit to Andrew for the max_sectors change.
That one's still pending.

The ERESTARTSYS one we were discussing here. I don't think that just
restarting the wait_event when we get a signal is the right approach.
It wouldn't allow the signal to be handled in all cases -- it happens
to work in the SIGCHLD case that we saw, since we don't really need to
handle that. But if nbd-client is sent a SIGKILL, for instance, it
should die. Just restarting the wait_event_interruptible doesn't allow
that. I think masking signals before we enter the NBD_DO_IT ioctl is
probably a better approach.

Sorry for the delays in my responses...I've been out on Easter break.

Thanks,
Paul
