Subject: uml: fix recvmsg return value checking
From: Jeff Dike <jdike@xxxxxxxxxxx>
Stupid bug - we need to compare the return value of recvmsg to the value of
iov_len, not its size. This caused port_helper processes not to be killed on
shutdown on x86_64 because the pids weren't being passed out properly.
