From c6650b2e57725abaa2e36e620d06fa576d26c21c Mon Sep 17 00:00:00 2001 From: Yaowei Bai Date: Tue, 29 Sep 2015 22:43:36 +0800 Subject: [PATCH] tracing: ftrace_event_is_function() can return boolean Make ftrace_event_is_function() return bool to improve readability due to this particular function only using either one or zero as its return value. No functional change.
