From mboxrd@z Thu Jan 1 00:00:00 1970 From: Eli Cohen Subject: [PATCH] mlx4_core: fix allocation size Date: Wed, 21 Sep 2011 16:31:17 +0300 Message-ID: <20110921133117.GA19540@mtldesk30> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Return-path: Content-Disposition: inline Sender: linux-rdma-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: roland-BHEL68pLQRGGvPXPguhicg@public.gmane.org Cc: RDMA list List-Id: linux-rdma@vger.kernel.org The num_free field of mlx4_buddy has a type of array of unsigned int while it was allocated as an array of pointers. On 64 bit platforms it would allocate twice more than required. Fix this by allocating the correct size for the type.
