From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: Subject: [PATCH v2 2/3] pci: Add pci_dev_flag for ACS enable quirks From: Alex Williamson To: bhelgaas@google.com, linux-pci@vger.kernel.org Cc: linux-kernel@vger.kernel.org Date: Mon, 03 Feb 2014 14:27:39 -0700 Message-ID: <20140203212739.8607.65523.stgit@bling.home> In-Reply-To: <20140203212216.8607.68273.stgit@bling.home> References: <20140203212216.8607.68273.stgit@bling.home> MIME-Version: 1.0 Content-Type: text/plain; charset="utf-8" Sender: linux-kernel-owner@vger.kernel.org List-ID: Quirks that enable ACS compatible functionality on a device need some way to track whether a given device has been enabled. Rather than create new data structures for this, allocate one of the pci_dev_flags to indicate this setup.
