From mboxrd@z Thu Jan 1 00:00:00 1970 From: Dennis Zhou Subject: [PATCH 11/13] blkcg: remove bio_disassociate_task() Date: Mon, 26 Nov 2018 16:19:44 -0500 Message-ID: <20181126211946.77067-12-dennis@kernel.org> References: <20181126211946.77067-1-dennis@kernel.org> Return-path: In-Reply-To: <20181126211946.77067-1-dennis@kernel.org> Sender: linux-kernel-owner@vger.kernel.org List-ID: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: Jens Axboe , Tejun Heo , Johannes Weiner , Josef Bacik Cc: kernel-team@fb.com, linux-block@vger.kernel.org, cgroups@vger.kernel.org, linux-kernel@vger.kernel.org, Dennis Zhou Now that a bio only holds a blkg reference, so clean up is simply putting back that reference. Remove bio_disassociate_task() as it just calls bio_disassociate_blkg() and call the latter directly.
