Subject: [PATCH] docs: lockdep-design: correct the notation for writer
Date: Fri, 21 May 2021 14:29:54 +0800 [thread overview]
Message-ID: <1621578594-13237-1-git-send-email-sxwjean@me.com> (raw)
From: Xiongwei Song <sxwjean@gmail.com>
The block condition matrix is using 'E' as the writer noation here, so it
would be better to use 'E' as the reminder rather than 'W'.
