From c851c8676bd7ae456e9b3af8e6bb2c434eddcc75 Mon Sep 17 00:00:00 2001 From: Miao Xie Date: Fri, 17 Oct 2008 18:17:46 +0800 Subject: sched: fix the wrong mask_len If NR_CPUS isn't a multiple of 32, we get a truncated string of sched domains by catting /proc/schedstat. This is caused by the wrong mask_len. This patch fixes it.
