Subject: [RFC PATCH 07/11] ext4: have sync_fs op report writeback errors when passed a since pointer
Date: Fri, 18 May 2018 08:34:11 -0400 [thread overview]
Message-ID: <20180518123415.28181-8-jlayton@kernel.org> (raw)
In-Reply-To: <20180518123415.28181-1-jlayton@kernel.org>
From: Jeff Layton <jlayton@redhat.com>
When ext4_sync_fs gets a non-NULL since pointer, use it to report
errors vs. the errseq_t in the super_block. This allows us to
properly report an error to sync_fs when any inode has failed writeback
since we last checked for it.
