@Zhang Zhuoyu: How about something like the following?
https://git.samba.org/?p=ddiss/linux.git;a=commitdiff;h=73723ccf433424721830797d70cfb88d4596e0fc

...this keeps the in_cmds metric, and renames tx/rx_cmds read/write_cmds
respectively. read/write_cmds is still a bit ambiguous, as it refers to
the command data direction rather than SCSI READ/WRITE CDBs, but IMO
it's clearer, and more consistent with the read/write_mbytes metrics.
