Subject: [PATCH] arch_numa: remove redundant nodemask clears in numa_init()
Date: Thu, 18 Jun 2026 01:39:19 +0900 [thread overview]
Message-ID: <20260617163919.2544899-1-ekffu200098@gmail.com> (raw)
numa_init() clears numa_nodes_parsed, node_possible_map and
node_online_map, then calls numa_memblks_init(), which clears the same
nodemasks. Nothing uses them in between.
These clears have been redundant since commit 767507654c22 ("arch_numa:
switch over to numa_memblks") made numa_init() use numa_memblks_init().
No functional change.
