Subject: [ndctl PATCH v9 05/13] daxctl/list: add target_node for device listings
Date: Wed, 31 Jul 2019 18:29:24 -0600 [thread overview]
Message-ID: <20190801002932.26430-6-vishal.l.verma@intel.com> (raw)
In-Reply-To: <20190801002932.26430-1-vishal.l.verma@intel.com>
The kernel provides a 'target_node' attribute for dax devices. When
converting a dax device to the system-ram mode, the memory is hotplugged
into this numa node. It would be helpful to print this in device
listings so that it is easy for applications to detect the node to
which the new memory belongs.
