From 99565a6c471cbb66caa68347c195133017559943 Mon Sep 17 00:00:00 2001 From: Fan Du Date: Thu, 15 Aug 2013 15:49:06 +0800 Subject: [PATCH] xfrm: Make xfrm_state timer monotonic xfrm_state timer should be independent of system clock change, so switch to CLOCK_BOOTTIME base which is not only monotonic but also counting suspend time. Thus issue reported in commit: 9e0d57fd6dad37d72a3ca6db00ca8c76f2215454 ("xfrm: SAD entries do not expire correctly after suspend-resume") could ALSO be avoided. v2: Use CLOCK_BOOTTIME to count suspend time, but still monotonic.
