    Subject[PATCH 29/47] block-rbd: Delete an unnecessary initialisation in rbd_img_obj_exists_submit()
    From
    Date
    From: Markus Elfring <elfring@users.sourceforge.net>
    Date: Mon, 12 Sep 2016 19:45:29 +0200

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