From c8a4522245e9931a53a98d5160bb4c00d3f73921 Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Tue, 22 Jul 2008 14:34:09 -0700 Subject: [PATCH] ipv6: use round_jiffies This timer normally happens once a minute, there is no need to cause an early wakeup for it, so align it to next second boundary to safe power. It can't be deferred because then it could take too long on cleanup or DoS. Signed-off-by: Stephen Hemminger Signed-off-by: David S.
