Subject: [for-next][PATCH 22/40] ftrace/x86_64: Have function graph tracer depend on DYNAMIC_FTRACE
Date: Fri, 22 Oct 2021 16:48:18 -0400	[thread overview]
Message-ID: <20211022204842.227202516@goodmis.org> (raw)
In-Reply-To: 20211022204756.099054287@goodmis.org

From: "Steven Rostedt (VMware)" <rostedt@goodmis.org>

The function graph tracer is going to now depend on
ARCH_SUPPORTS_FTRACE_OPS, as that also means that it can support ftrace
args. Since ARCH_SUPPORTS_FTRACE_OPS depends on DYNAMIC_FTRACE, this
means that the function graph tracer for x86_64 will need to depend on
DYNAMIC_FTRACE.
