Subject: [PATCH v4 07/16] fsnotify: Add helper to detect overflow_event
Date: Tue, 20 Jul 2021 11:59:35 -0400 [thread overview]
Message-ID: <20210720155944.1447086-8-krisman@collabora.com> (raw)
In-Reply-To: <20210720155944.1447086-1-krisman@collabora.com>
Similarly to fanotify_is_perm_event and friends, provide a helper
predicate to say whether a mask is of an overflow event.
