From mboxrd@z Thu Jan 1 00:00:00 1970 From: Christoph Hellwig Subject: [PATCH 13/17] md: remove md_bio_alloc_sync Date: Tue, 26 Jan 2021 15:52:43 +0100 Message-ID: <20210126145247.1964410-14-hch@lst.de> References: <20210126145247.1964410-1-hch@lst.de> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: In-Reply-To: <20210126145247.1964410-1-hch@lst.de> List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Sender: dm-devel-bounces@redhat.com Errors-To: dm-devel-bounces@redhat.com To: Jens Axboe , Song Liu Cc: Mike Snitzer , David Sterba , dm-devel@redhat.com, Naohiro Aota , linux-nilfs@vger.kernel.org, Josef Bacik , Chao Yu , linux-nfs@vger.kernel.org, Coly Li , linux-raid@vger.kernel.org, linux-bcache@vger.kernel.org, drbd-dev@tron.linbit.com, Jaegeuk Kim , Ryusuke Konishi , linux-block@vger.kernel.org, Damien Le Moal , Andrew Morton , linux-mm@kvack.org, Philipp Reisner , linux-f2fs-devel@lists.sourceforge.net, linux-fsdevel@vger.kernel.org, Lars Ellenberg , linux-btrfs@vger.kernel.org md_bio_alloc_sync is never called with a NULL mddev, and ->sync_set is initialized in md_run, so it always must be initialized as well. Just open code the remaining call to bio_alloc_bioset.
