Subject: [PATCH] fgraph: Change the name of cpuhp state to "fgraph:online"
Date: Thu, 24 Oct 2024 22:29:44 -0400 [thread overview]
Message-ID: <20241024222944.473d88c5@rorschach.local.home> (raw)
From: Steven Rostedt <rostedt@goodmis.org>
The cpuhp state name given to cpuhp_setup_state() is "fgraph_idle_init"
which doesn't really conform to the names that are used for cpu hotplug
setups. Instead rename it to "fgraph:online" to be in line with other
states.
Suggested-by: Masami Hiramatsu <mhiramat@kernel.org>
Fixes: 2c02f7375e658 ("fgraph: Use CPU hotplug mechanism to initialize idle shadow stacks")
