From: Jorgen Hansen Date: Tue, 19 Apr 2016 06:58:52 +0000 (-0700) Subject: VSOCK: Only check error on skb_recv_datagram when skb is NULL X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9c995cc9a206a008699da82f6cd01e9b2615649a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git VSOCK: Only check error on skb_recv_datagram when skb is NULL If skb_recv_datagram returns an skb, we should ignore the err value returned. Otherwise, datagram receives will return EAGAIN when they have to wait for a datagram. Acked-by: Adit Ranadive Signed-off-by: Jorgen Hansen Signed-off-by: David S.
