Message-Id: <1425923742-4488-3-git-send-email-jeffrey.t.kirsher@intel.com> Date: Mon, 9 Mar 2015 10:55:35 -0700 From: Jeff Kirsher <jeffrey.t.kirsher@...el.com> To: davem@...emloft.net Cc: Shannon Nelson <shannon.nelson@...el.com>, netdev@...r.kernel.org, nhorman@...hat.com, sassmann@...hat.com, jogreene@...hat.com, Jeff Kirsher <jeffrey.t.kirsher@...el.com> Subject: [net-next 2/9] i40e: future proof some sizeof calls From: Shannon Nelson <shannon.nelson@...el.com> Make sure the sizeof() calls are taking the size of the actual struct that we care about. By using the pointer variable, we'll always get the right struct size, even if the variable type changes sometime in the future.
