SubjectRe: [PATCH 1/1] target:separate tx/rx cmd_puds
Hi,

The commit summary has a typo (cmd_puds). That said, this change
isn't iSCSI specific, so using "pdu" here doesn't make much sense IMO.

I don't think the in_cmds metric should be deleted here. It could be
calculated on the fly via tx_cmds + rx_cmds + nodata_cmds.
