Subject: [FIX PATCH 0/2] Fix NUMA nodes fallback list ordering
Date: Mon, 30 Aug 2021 17:46:01 +0530 [thread overview]
Message-ID: <20210830121603.1081-1-bharata@amd.com> (raw)
For a NUMA system that has multiple nodes at same distance from
other nodes, the fallback list generation prefers same node order
for them instead of round-robin thereby penalizing one node over
others. This series fixes it.
More description of the problem and the fix is present in the
patch description.
