Subject: [PATCH v2 4/5] device-dax/kmem: Set node state as N_DEMOTION_TARGETS
Date: Wed, 13 Apr 2022 14:52:05 +0530 [thread overview]
Message-ID: <20220413092206.73974-5-jvgediya@linux.ibm.com> (raw)
In-Reply-To: <20220413092206.73974-1-jvgediya@linux.ibm.com>
Set dax-device node as N_DEMOTION_TARGETS so that it
can be used as demotion target.
In future, support should be added to distinguish the
dax-devices which are not preferred as demotion target
e.g. HBM, for such devices, node shouldn't be set to
N_DEMOTION_TARGETS.
