Subject: [PATCH v13 02/13] eventfd: Export eventfd_wake_count to modules
Date: Tue, 31 Aug 2021 18:36:23 +0800 [thread overview]
Message-ID: <20210831103634.33-3-xieyongji@bytedance.com> (raw)
In-Reply-To: <20210831103634.33-1-xieyongji@bytedance.com>
Export eventfd_wake_count so that some modules can use
the eventfd_signal_count() to check whether the
eventfd_signal() call should be deferred to a safe context.
