The patch titled
Subject: mm: sched: numa: fix NUMA balancing when !SCHED_DEBUG
has been removed from the -mm tree. Its filename was
mm-sched-numa-fix-numa-balancing-when-sched_debug.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Dave Kleikamp <dave.kleikamp@xxxxxxxxxx>
Subject: mm: sched: numa: fix NUMA balancing when !SCHED_DEBUG
3105b86a ("mm: sched: numa: Control enabling and disabling of NUMA
balancing if !SCHED_DEBUG") defined numabalancing_enabled to control the
enabling and disabling of automatic NUMA balancing, but it is never used.
I believe the intention was to use this in place of sched_feat_numa(NUMA).
Currently, if SCHED_DEBUG is not defined, sched_feat_numa(NUMA) will never
be changed from the initial "false".
