This is a "common" structure but many of the components refer to sli-rev specific entities which can lead the developer astray as to what they actually mean, should be set to, or when they should be used. This first patch prepares the lpfc_iocbq structure so that elements common to both SLI3 and SLI4 data paths are more appropriately named, making it clear they apply generically. Fieldnames based on 'iocb' (sli3) or 'wqe' (sli4) which are actually generic to the paths are renamed to 'cmd': - iocb_flag is renamed to cmd_flag - lpfc_vmid_iocb_tag is renamed to lpfc_vmid_tag - fabric_iocb_cmpl is renamed to fabric_cmd_cmpl - wait_iocb_cmpl is renamed to wait_cmd_cmpl - iocb_cmpl and wqe_cmpl are combined and renamed to cmd_cmpl - rsvd2 member is renamed to num_bdes due to pre-existing usage The structure name itself will retain the iocb reference as changing to a more relevant "job" or "cmd" title induces many hundreds of line changes for only a name change. lpfc_post_buffer is also renamed to lpfc_sli3_post_buffer to indicate use in the SLI3 path only.

| * | scsi: libsas: Add sas_execute_internal_abort_single()John Garry2022-03-151-0/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The internal abort feature is common to hisi_sas and pm8001 HBAs, and the driver support is similar also, so add a common handler. Two modes of operation will be supported: - single: Abort a single tagged command - device: Abort all commands associated with a specific domain device A new protocol is added, SAS_PROTOCOL_INTERNAL_ABORT, so the common queue command API may be re-used. Only add "single" support as a first step.
