Subject: [PATCH 26/28] hazptrtorture: Add torture_type=none clean skip for rcuscale coexistence
Date: Thu, 5 Nov 2026 00:54:44 +0800 [thread overview]
Message-ID: <20261104165504.2430480-27-kunwu.chan@gmail.com> (raw)
In-Reply-To: <20261104165504.2430480-1-kunwu.chan@gmail.com>
When both HAZPTR_TORTURE_TEST and RCU_SCALE_TEST are built into
the same kernel, hazptrtorture calls torture_init_begin() first
and rcuscale fails with -EBUSY. torture_type=none makes
hazptrtorture return early without registering, allowing the
rcuscale hazptr scale type to run in the same boot.
