From 2c64580046a122fa15bb586d8ca4fd5e4b69a1e7 Mon Sep 17 00:00:00 2001 From: stephen hemminger Date: Thu, 22 Dec 2011 08:52:03 +0000 Subject: [PATCH] netlink: wake up netlink listeners sooner (v2) This patch changes it to yield sooner at halfway instead. Still not a cure-all for listener overrun if listner is slow, but works much reliably. Signed-off-by: Stephen Hemminger Signed-off-by: David S.
