Subject: [PATCH v2 09/17] libnvdimm, pmem: fix up max_hw_sectors
Date: Thu, 25 Jun 2015 05:37:06 -0400 [thread overview]
Message-ID: <20150625093706.40066.60886.stgit@dwillia2-desk3.jf.intel.com> (raw)
In-Reply-To: <20150625090554.40066.69562.stgit@dwillia2-desk3.jf.intel.com>
There is no hardware limit to enforce on the size of the i/o that can be passed
to an nvdimm block device, so set it to UINT_MAX.
