Subject: [ndctl PATCH v2 17/26] ndctl/test: Checkout device-mapper + dax operation
Date: Sat, 27 Jul 2019 14:40:52 -0700	[thread overview]
Message-ID: <156426365289.531577.3024221395183254159.stgit@dwillia2-desk3.amr.corp.intel.com> (raw)
In-Reply-To: <156426356088.531577.14828880045306313118.stgit@dwillia2-desk3.amr.corp.intel.com>

Given recent kernel changes broke the device-mapper use case, introduce
a basic unit test to prevent this from regressing in the future.
