Subject: [for-next][PATCH 24/34] ftrace: Use true and false for boolean values in ops_references_rec()
Date: Sat, 11 Aug 2018 09:49:52 -0400	[thread overview]
Message-ID: <20180811135015.412405474@goodmis.org> (raw)
In-Reply-To: 20180811134928.034373761@goodmis.org

From: "Gustavo A. R. Silva" <gustavo@embeddedor.com>

Return statements in functions returning bool should use true or false
instead of an integer value.

This code was detected with the help of Coccinelle.
