Subject: [for-next][PATCH 06/12] tracing: Move is_good_name() from trace_probe.h to trace.h
Date: Wed, 14 Oct 2020 13:36:53 -0400	[thread overview]
Message-ID: <20201014173728.961779933@goodmis.org> (raw)
In-Reply-To: 20201014173647.955053902@goodmis.org

From: Tom Zanussi <zanussi@kernel.org>

is_good_name() is useful for other trace infrastructure, such as
synthetic events, so make it available via trace.h.
