From 8ccde4c562076f280c0321c549d822448b64e565 Mon Sep 17 00:00:00 2001 From: Gao Feng Date: Tue, 21 Feb 2017 17:09:19 +0800 Subject: [PATCH] net: sock: Use USEC_PER_SEC macro instead of literal 1000000 The USEC_PER_SEC is used once in sock_set_timeout as the max value of tv_usec. But there are other similar codes which use the literal 1000000 in this file. It is minor cleanup to keep consitent. Signed-off-by: Gao Feng Signed-off-by: David S.
