Subject: [PATCH 01/15] dax: quiet bdev_dax_supported()
Date: Tue, 31 Oct 2017 16:21:40 -0700 [thread overview]
Message-ID: <150949210033.24061.4289855641340001687.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <150949209290.24061.6283157778959640151.stgit@dwillia2-desk3.amr.corp.intel.com>
Before we add another failure reason, quiet the existing log messages.
Leave it to the caller to decide if bdev_dax_supported() failures are
errors worth emitting to the log.
