From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Johan Hedberg To: linux-bluetooth@vger.kernel.org Subject: [PATCH 08/15] Bluetooth: Rename conn->pend to conn->flags Date: Wed, 18 Jan 2012 20:51:50 +0200 Message-Id: <1326912717-6347-9-git-send-email-johan.hedberg@gmail.com> In-Reply-To: <1326912717-6347-1-git-send-email-johan.hedberg@gmail.com> References: <1326912717-6347-1-git-send-email-johan.hedberg@gmail.com> Sender: linux-bluetooth-owner@vger.kernel.org List-ID: From: Johan Hedberg These flags can and will be used for more general purpose values than just pending state transitions so the more common name "flags" makes more sense than "pend".
