Subject: [PATCH] srcutree: Skip torture to-big transition for atomic SRCU
Date: Thu, 10 Sep 2026 12:14:27 +0800	[thread overview]
Message-ID: <20260910041427.3579817-1-kunwu.chan@gmail.com> (raw)

Atomic SRCU does not use the srcu_node combining tree.  Exclude it
from the SRCU_SIZING_IS_TORTURE() transition in
srcu_torture_stats_print().
