Subject: [PATCH v2 0/4] scsi: libsas and users: Factor out internal abort code

This is a follow-on from the series to factor out the TMF code shared
between libsas LLDDs.

The hisi_sas and pm8001 have an internal abort feature to abort pending
commands in the host controller, prior to being sent to the target. The
driver support implementation is naturally quite similar, so factor it
out.

Again, testing and review would be appreciated.

This is based on mkp-scsi 5.18 staging queue @ commit 2bd3b6b75946

Changes since v1:
- fixup small coding issues (Damien)
- Add Tested-by tags (thanks!)

John Garry (4):
  scsi: libsas: Add sas_execute_internal_abort_single()
  scsi: libsas: Add sas_execute_internal_abort_dev()
  scsi: pm8001: Use libsas internal abort support
  scsi: hisi_sas: Use libsas internal abort support
