Subject: [PATCH v2 01/12] s390/percpu: Fix comment typo
Date: Fri, 18 Sep 2026 10:48:31 +0200 [thread overview]
Message-ID: <20260918084842.2333237-2-hca@linux.ibm.com> (raw)
In-Reply-To: <20260918084842.2333237-1-hca@linux.ibm.com>
This is all preempt_disable() / preempt_enable() pairs and not
preempt_disable() / preempt_disable() pairs.
