4.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Pavel Shilovsky <pshilov@xxxxxxxxxxxxx> commit ee13919c2e8d1f904e035ad4b4239029a8994131 upstream. Currently we hide EINTR code returned from sock_sendmsg() and return 0 instead. This makes a caller think that we successfully completed the network operation which is not true. Fix this by properly returning EINTR to callers.
