--- Comment #4 from Dexuan Cui <decui at microsoft.com> ---
2 patches are committed into the CURRENT to improve the situation:

commit 2d2d5090052a987069c501ea3a7b73691347dae1

    hyperv/stor: Save the response status and xfer length properly.

    The current command response handling discards status and xfer
    length unconditionally, so that all of the commands would be
    considered successful, even if errors happened.  When errors
    really happens, this causes all kinds of wiredness, since the
    buffer will not be filled on the host side and sense data will
    be ignored.

    Most of the time, errors do not happen, however, error does
    happen for the request sent immediately after the disk resizing.
    Discarding the SCSI status (SCSI_STATUS_CHECK_COND) and sense
    data (capacity changes) prevents the disk resizing from working
    properly.

    This commit saves the response status and xfer length properly
    for later use.
