Subject: [PATCH v3 1/3] fs: direct-io: handle error in dio_end_io()
Date: Thu, 28 Apr 2016 09:09:47 +0800	[thread overview]
Message-ID: <1461805789-3632-1-git-send-email-ming.lei@canonical.com> (raw)

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().
