Cc: linux-xfs@xxxxxxxxxxxxxxx, "Darrick J. Wong" <darrick.wong@xxxxxxxxxx>
Message-ID: <1486022171-8076-6-git-send-email-hch@xxxxxx>
From: Christoph Hellwig <hch@xxxxxx>
commit 84a4620cfe97c9d57e39b2369bfb77faff55063d upstream.
There are only two reasons for xfs_log_force / xfs_log_force_lsn to fail:
one is an I/O error, for which xlog_bdstrat already logs a warning, and
the second is an already shutdown log due to a previous I/O errors. In
the latter case we'll already have a previous indication for the actual
error, but the large stream of misleading warnings from xfs_log_force
will probably scroll it out of the message buffer.
Simply removing the warnings thus makes the XFS log reporting significantly
better.
