From 2b2842146cb4105877c2be51d3857ec61ebd4ff9 Mon Sep 17 00:00:00 2001 From: Arjan van de Ven <arjan@linux.intel.com> Date: Sun, 10 Dec 2006 02:21:28 -0800 Subject: [PATCH] user of the jiffies rounding patch: Slab This patch introduces users of the round_jiffies() function in the slab code. The slab code has a few "run every second" timers for background work; these are obviously not timing critical as long as they happen roughly at the right frequency.
