Subject: [PATCH -tip  1/4] tracing: change tracer's integer flags to bool
Date: Tue, 02 Oct 2012 17:27:10 +0900	[thread overview]
Message-ID: <20121002082710.9807.86393.stgit@falsita> (raw)
In-Reply-To: <20121002081309.8661.37629.stgit@falsita>

print_max and use_max_tr in struct tracer are "int" variables and
used like flags. This is wasteful, so change the type to "bool".
