Subject: [RFC PATCH 03/11] vfs: add an errseq_t pointer to sync_filesystem
Date: Fri, 18 May 2018 08:34:07 -0400
Message-Id: <20180518123415.28181-4-jlayton@kernel.org>
In-Reply-To: <20180518123415.28181-1-jlayton@kernel.org>
References: <20180518123415.28181-1-jlayton@kernel.org>
Sender: linux-fsdevel-owner@vger.kernel.org
List-ID: <linux-fsdevel.vger.kernel.org>

From: Jeff Layton <jlayton@redhat.com>

Allow sync_filesystem to take an errseq_t for the purposes of error
reporting. This value is just passed directly to the ->sync_fs op.
