| |
2.6.27-stable review patch. If anyone has any objections, please let us know.
------------------ From: Miao Xie <miaox@cn.fujitsu.com>
commit c851c8676bd7ae456e9b3af8e6bb2c434eddcc75 upstream
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.
