Subject: [PATCH 5/8] futex: add wake_data to struct futex_q
Date: Wed, 12 Jul 2023 10:20:14 -0600 [thread overview]
Message-ID: <[email protected]> (raw)
In-Reply-To: <[email protected]>
With handling multiple futex_q for waitv, we cannot easily go from the
futex_q to data related to that request or queue. Add a wake_data
argument that belongs to the wake handler assigned.
