Hmm.
I think the "goto unlock_out" should be a "break". A partial read
should return the partial success, not an error.
That situation didn't exist when the check was outside the loop, but does now.
Now, I don't think this matters for any sane situation, but since I
looked at this patch I thought I'd mention it.
Fair enough, George, can you send a follow-on patch to fix this up?
Hi Greg,
Will send a follow-on patch.
Thanks,
George
