Subject: [PATCH] Documentation/cgroups/blkio-controller.txt: s/disk_time|disk_sectors/time|sectors/

Hello,

For blkio controller of cgroup, both disk_time and disk_sectors were
obsolated file names. Now we're using blkio.time and blkio.sectors to
examine how much disk time each cgroup got and how many sectors each
cgroup dispatched separately.

This patch fix the document to reflect those changes as well as a couple
of typos(secotors and io.disk_time).

Thanks,
-Jeff

- At macro level, first dd should finish first. To get more precise data, keep
