Subject: [PATCH v2 2/4] slub: Actually use 'message' in restore_bytes()
Date: Tue, 25 May 2021 19:56:23 -0700 [thread overview]
Message-ID: <20210526025625.601023-3-swboyd@chromium.org> (raw)
In-Reply-To: <20210526025625.601023-1-swboyd@chromium.org>
The message argument isn't used here. Let's pass the string to the
printk message so that the developer can figure out what's happening,
instead of guessing that a redzone is being restored, etc.
