    Subject[REPOST PATCH v4 0/3] scsi: ufs-bsg: Add read descriptor
    Date
    UFS Protocol Information Units (UPIU) are UFS packets that travel
    between the host and the device on the UniPro bus. Our previous series
    added the capability to send UPIUs to the ufs driver. It does not cover
    all the possible UPIU types - we are mainly focused on device management,
    provisioning, testing and validation, so it covers UPIUs that falls in
    that box.

    Our intension is to publish ufs-utils soon - an open source user space
    utility that relies on that infrastructure to perform those tasks.
    This short series is adding one last functionality needed by ufs-utils
    that was somehow left behind - allowing reading descriptors as well.

    Repost of v4 and adds tags already received.
    While at it, it turns out that quite a few people are waiting for
    ufs-utils, e.g. https://www.spinics.net/lists/linux-scsi/msg127807.html.
    So I expect that the small, but vibrant community of ufs users, will try
    to expand this infrastructure even further.

    V3->v4:
    Improve code readability in ufs-bsg: Allow reading descriptors
    Update Reviewed-by tag.

    V2->v3:
    Add a prep patch with write descriptor calling convention changes.
    Elaborate the commit log of ufs-bsg: Allow reading descriptors
    Add Reviewed-by tag.

    v1->v2:
    Withdraw from the attempt to change the reply buffer, instead place the
    descriptor being read in the actual data buffer in the bio.
