Subject: [PATCH v3 4/7] device-dax/kmem: Set node state as N_DEMOTION_TARGETS
Date: Sat, 23 Apr 2022 01:25:13 +0530	[thread overview]
Message-ID: <20220422195516.10769-5-jvgediya@linux.ibm.com> (raw)
In-Reply-To: <20220422195516.10769-1-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.
