Subject: [PATCH] block: Initialize max_dev_sectors to 0
Date: Wed, 10 Feb 2016 16:52:47 -0700	[thread overview]
Message-ID: <1455148367-25208-1-git-send-email-keith.busch@intel.com> (raw)

The new queue limit is not used by the majority of block drivers, and
should be initialized to 0 for the driver's requested settings to be used.
