    Subject[PATCH 13/47] block-rbd: Delete an unnecessary initialisation in rbd_dev_v2_parent_info()
    From
    Date
    From: Markus Elfring <elfring@users.sourceforge.net>
    Date: Mon, 12 Sep 2016 18:08:14 +0200

    The local variable "reply_buf" will be set to an appropriate pointer
    a bit later. Thus omit the explicit initialisation at the beginning.
