Date: Thu, 28 Apr 2016 09:09:47 +0800 From: Ming Lei <ming.lei@...onical.com> To: Jens Axboe <axboe@...com>, linux-kernel@...r.kernel.org Cc: linux-block@...r.kernel.org, Christoph Hellwig <hch@...radead.org>, linux-btrfs@...r.kernel.org, Ming Lei <ming.lei@...onical.com>, Alexander Viro <viro@...iv.linux.org.uk>, linux-fsdevel@...r.kernel.org (open list:FILESYSTEMS (VFS and infrastructure)) Subject: [PATCH v3 1/3] fs: direct-io: handle error in dio_end_io() If error is passed to dio_end_io(), it should have been dealt with. Unfortunately current code just ignores that silently. Only btrfs uses dio_end_io().
