    Subject[PATCH 5.10 20/84] scsi: vmw_pvscsi: Expand vcpuHint to 16 bits
    Date
    From: Wentao Wang <wwentao@vmware.com>

    [ Upstream commit cf71d59c2eceadfcde0fb52e237990a0909880d7 ]

    vcpuHint has been expanded to 16 bit on host to enable routing to more
    CPUs. Guest side should align with the change. This change has been tested
    with hosts with 8-bit and 16-bit vcpuHint, on both platforms host side can
    get correct value.
