    Subject[PATCH v4 0/5] hisi_sas: DIF support
    Date
    This patchset introduces support to the driver for DIF/DIX.

    We are making DIX support as RFC for now, based on issues discussed in the
    following:
    https://marc.info/?l=linux-scsi&m=154357719329297&w=4 and
    https://marc.info/?l=linux-scsi&m=154406987703456&w=2

    We will only support PI in v3 hw at the moment, even though previous hw
    versions also support it.

    The series is broken down as follows:
    - Fix pre-existing sparse warnings
    - Tidy sg table size config
    - Some tidy-up to accept PI support
    - Add components for PI support for main and v3 driver

    Differences:
    v3->v4:
    - re-add DIX support as RFC - do not commit please!
    - also DIX support is labelled experimental in the driver

    v2->v3:
    - fix sparse warnings
    - drop DIX support

    v1->v2:
    - drop scsi_prot_op_normal()

    John Garry (1):
    scsi: hisi_sas: Fix warnings detected by sparse

    Xiang Chen (4):
    scsi: hisi_sas: Relocate some code to reduce complexity
    scsi: hisi_sas: Make sg_tablesize consistent value
    scsi: hisi_sas: Add support for DIF feature for v3 hw
    scsi: hisi_sas: Add support for DIX feature for v3 hw as experimental
