Subject: [PULL 01/11] trace: fix simpletrace doc mismerge
Date: Mon, 1 Feb 2021 15:46:53 +0000 [thread overview]
Message-ID: <20210201154703.180022-2-stefanha@redhat.com> (raw)
In-Reply-To: <20210201154703.180022-1-stefanha@redhat.com>
The simpletrace documentation section was accidentally split when the
ftrace section was introduced. Move the simpletrace-specific
documentation back into the simpletrace section.
Fixes: e64dd5efb2c6d522a3bc9d096cd49a4e53f0ae10 ("trace: document ftrace backend")
Reviewed-by: Peter Maydell <peter.maydell@linaro.org>
