PATCH 1/1 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
