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. Signed-off-by: Miao Xie <miaox@cn.fujitsu.com> Cc: <stable@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
