[PATCH 4.9 37/51] xfs: dont print warnings when xfs_log_force fails

From: Greg Kroah-Hartman
Date: Thu Feb 02 2017 - 13:44:45 EST


4.9-stable review patch. If anyone has any objections, please let me know.

------------------

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.
