Subject: [PATCH 5/5] rcutorture: Add KASAN aux-stack verification scenarios
Date: Fri, 6 Nov 2026 22:39:13 +0800 [thread overview]
Message-ID: <20261106143913.3627722-6-kunwu.chan@gmail.com> (raw)
In-Reply-To: <20261106143913.3627722-1-kunwu.chan@gmail.com>
Add one rcutorture scenario per RCU flavor for the aux-stack
verification test: TASKSKASAN01, TREEKASAN01, TINYKASAN01,
SRCUKASAN01, and SRCUTINYKASAN01. Each sets CONFIG_KASAN=y,
CONFIG_RCU_KASAN_AUX_TEST=y, the appropriate flavor choice, and
the kernel config needed for that RCU implementation.
