From db6e3e8d016823c6b0f773c70a69ce65807d8a44 Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Mon, 30 Mar 2015 23:21:02 +0300 Subject: Bluetooth: Refactor HCI request variables into own struct In order to shrink the size of bt_skb_cb, this patch moves the HCI request related variables into their own req_ctrl struct. Additionall the L2CAP and HCI request structs are placed inside the same union since they will never be used at the same time for the same skb.
