Subject: [Patch RFC 1/2] tracing: allow disabling compilation of specific trace systems
Date: Sat, 20 Jun 2015 23:21:18 +0300 [thread overview]
Message-ID: <1434831679-3852-2-git-send-email-tal.shorer@gmail.com> (raw)
In-Reply-To: <1434831679-3852-1-git-send-email-tal.shorer@gmail.com>
Allow a trace events header file to disable compilation of its
trace events by defining the preprocessor macro NOTRACE.
This could be done, for example, according to a Kconfig option.
