Description of problem:

There appears to have been a repeated cut'n'paste error where time or number fields were confused with byte fields (conflict in CAPS).

"blkio.io_serviced
   reports the number of I/O operations performed on specific devices by a cgroup. Entries have four fields: major, minor, operation, and BYTES. Major and minor are device types and node numbers specified in Linux Allocated Devices, operation represents the type of operation (read, write, sync, or async) and NUMBER represents the number of operations."

"blkio.io_service_time
   reports the total time between request dispatch and request completion for I/O operations on specific devices by a cgroup. Entries have four fields: major, minor, operation, and BYTES.  Major and minor are device types and node numbers specified in Linux Allocated Devices, operation represents the type of operation (read, write, sync, or async) and TIME is the length of time in nanoseconds (ns)."

"blkio.io_wait_time
   ...Entries have four fields: major, minor, operation, and BYTES. Major and minor are device types and node numbers specified in Linux Allocated Devices, operation represents the type of operation (read, write, sync, or async) and TIME is the length of time in nanoseconds (ns)..."
