Subject: [PATCH 1/3] ftrace: simplify the Kconfig dependency of FTRACE
Date: Sat, 31 Jul 2021 14:22:31 +0900	[thread overview]
Message-ID: <20210731052233.4703-1-masahiroy@kernel.org> (raw)

The entire FTRACE block is surrounded by 'if TRACING_SUPPORT' ...
'endif'.

Using 'depends on' is a simpler way to guard FTRACE.
