I know, but I'd really not have subtily different calling conventions
between the two.
Right now transport_cmd_finish_abort and transport_cmd_finish_abort_tmr
only differ in:
- transport_cmd_finish_abort calling transport_lun_remove_cmd
- transport_cmd_finish_abort having the remove flag to make the
transport_put_cmd (and with your patch the
transport_remove_cmd_from_queue) call optional.
I'd much rather add a conditional on the command beeing a TMR and merge
the two into a single helper than having them diverge further.
