Subject: [PATCH 2/6] pmem: Add support for getgeo()
Date: Mon, 16 Mar 2015 15:12:56 -0600	[thread overview]
Message-ID: <1426540380-24503-3-git-send-email-ross.zwisler@linux.intel.com> (raw)
In-Reply-To: <1426540380-24503-1-git-send-email-ross.zwisler@linux.intel.com>

Some programs require HDIO_GETGEO work, which requires we implement
getgeo.  Based off of the work done to the NVMe driver in this commit:

commit 4cc09e2dc4cb ("NVMe: Add getgeo to block ops")
