From mboxrd@z Thu Jan 1 00:00:00 1970 From: Christoph Hellwig Subject: [RFC] add a bi_error field Date: Wed, 3 Jun 2015 15:42:38 +0200 Message-ID: <1433338959-24808-1-git-send-email-hch@lst.de> Return-path: Sender: linux-btrfs-owner@vger.kernel.org To: Jens Axboe Cc: linux-raid@vger.kernel.org, linux-btrfs@vger.kernel.org, dm-devel@redhat.com List-Id: linux-raid.ids Bio error reporting has been a mess for a while, and the increasing use of chained bios makes it worse. This series attempts to add a proper error field to struct bio to sort this out. It's working fine for me, but MD and btrfs were doing pretty nasty things with the BIO_UPTODATE flag, so I would appreciate some detailed review there.
