Subject: [PATCH 2/7] fsnotify: Add missing annotation for fsnotify_finish_user_wait()
Date: Tue, 31 Mar 2020 21:46:38 +0100	[thread overview]
Message-ID: <20200331204643.11262-3-jbi.octave@gmail.com> (raw)
In-Reply-To: <20200331204643.11262-1-jbi.octave@gmail.com>

Sparse reports a warning at fsnotify_finish_user_wait()

warning: context imbalance in fsnotify_finish_user_wait()
	- wrong count at exit

The root cause is the missing annotation at fsnotify_finish_user_wait()
Add the missing __acquires(&fsnotify_mark_srcu) annotation.
