Subject: [PATCH 09/13] rcutorture: Disable srcu_expedite_current() for atomic SRCU
Date: Mon, 7 Sep 2026 15:58:25 +0800 [thread overview]
Message-ID: <20260907075829.2073224-10-kunwu.chan@linux.dev> (raw)
In-Reply-To: <20260907075829.2073224-1-kunwu.chan@linux.dev>
From: Kunwu Chan <kunwu.chan@gmail.com>
srcu_expedite_current() is now forbidden for atomic SRCU, so null out
->exp_current in srcu_torture_init_forbidden_apis().
