Subject: [PATCH v3 01/13] dax: quiet bdev_dax_supported()
Date: Thu, 19 Oct 2017 19:39:02 -0700	[thread overview]
Message-ID: <150846714231.24336.100401563090934098.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <150846713528.24336.4459262264611579791.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.
