    Subject[PATCH v1 0/4] Add ioctl and debug utilities to UFS driver
    Date
    This patch series introduces in the first change a new UFS ioctl,
    allowing user-space to send UFS queries and retrieve information from them.
    In addition, the other three patches add utilities to support debugging
    efforts and supply information that will help analysis of issue:
    UFS trace events, dump host controller registers and requests descriptors
    on failures, several statistics.

    Dolev Raviv (1):
    scsi: ufs: add ioctl interface for query request

    Gilad Broner (1):
    scsi: ufs: add trace events and dump prints for debug

    Lee Susman (1):
    scsi: ufs: add debugfs for ufs

    Sujit Reddy Thumma (1):
    scsi: ufs: inject errors to verify error handling
