Subject: [PATCH 05/13] srcutree: Honor is_atomic in check_init_srcu_struct()
Date: Mon, 7 Sep 2026 15:58:21 +0800 [thread overview]
Message-ID: <20260907075829.2073224-6-kunwu.chan@linux.dev> (raw)
In-Reply-To: <20260907075829.2073224-1-kunwu.chan@linux.dev>
From: Kunwu Chan <kunwu.chan@gmail.com>
check_init_srcu_struct() drops its is_atomic argument, passing
hard-coded false to init_srcu_struct_fields(). Pass is_atomic through
instead.
