Subject: [PATCH] trace/recordmcount: add the necessary dependencies
Date: Wed, 12 Apr 2023 18:18:40 +0800	[thread overview]
Message-ID: <20230412101840.13601-1-sunying@nj.iscas.ac.cn> (raw)

From: Ying Sun <sunying@nj.iscas.ac.cn>

HAVE_C_RECORDMCOUNT is used only if the condition
"ifdef CONFIG_FTRACE_MCOUNT_USE_RECORDMCOUNT" is met in the Makefile,
adding a dependency constraint on this configuration option
 to prevent it from being set ‘y' but not taking effect.
