[Andrew Morton]

     Subject: mm: cleanup WORKINGSET_NODES in workingset
has been removed from the -mm tree.  Its filename was

Subject: mm: cleanup WORKINGSET_NODES in workingset
Date: Wed, 1 May 2024 10:26:15 -0700

WORKINGSET_NODES is not exposed in the memcg stats and thus there is no
need to use the memcg specific stat update functions for it.  In future if
we decide to expose WORKINGSET_NODES in the memcg stats, we can revert
this patch.
