Subject: [PATCH 3/7] dax: Add missing annotation for wait_entry_unlocked()
Date: Tue, 31 Mar 2020 21:46:39 +0100 [thread overview]
Message-ID: <20200331204643.11262-4-jbi.octave@gmail.com> (raw)
In-Reply-To: <20200331204643.11262-1-jbi.octave@gmail.com>
Sparse reports a warning at wait_entry_unlocked()
warning: context imbalance in wait_entry_unlocked()
- unexpected unlock
The root cause is the missing annotation at wait_entry_unlocked()
Add the missing __releases(xa) annotation.
