From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jeff Layton Date: Tue, 9 May 2017 11:49:12 -0400 Subject: [Cluster-devel] [PATCH v4 09/27] nilfs2: set the mapping error when calling SetPageError on writeback In-Reply-To: <20170509154930.29524-1-jlayton@redhat.com> References: <20170509154930.29524-1-jlayton@redhat.com> Message-ID: <20170509154930.29524-10-jlayton@redhat.com> List-Id: To: cluster-devel.redhat.com MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit In a later patch, we're going to want to make the fsync codepath not do a TestClearPageError call as that can override the error set in the address space. To do that though, we need to ensure that filesystems that are relying on the PG_error bit for reporting writeback errors also set an error in the address space. Ensure that this is set in nilfs2.
