From: Bob Peterson Date: Wed, 22 Apr 2015 16:24:12 +0000 (-0500) Subject: GFS2: Average in only non-zero round-trip times for congestion stats X-Git-Tag: omap-for-v4.2/fixes-rc1^2~84^2~14 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0166b197c2ed;p=pandora-kernel.git GFS2: Average in only non-zero round-trip times for congestion stats This patch changes function gfs2_rgrp_congested so that it only factors in non-zero values into its average round trip time. If the round-trip time is zero for a particular cpu, that cpu has obviously never dealt with bouncing the resource group in question, so factoring in a zero value will only skew the numbers. It also fixes a compile error on some arches related to division. Signed-off-by: Bob Peterson Acked-by: Steven Whitehouse --- Reading git-diff-tree failed
