    Subject[PATCH 4.9 02/16] CIFS: Do not hide EINTR after sending network packets
    Date
    4.9-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Pavel Shilovsky <pshilov@microsoft.com>

    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.
