Subject: [for-linus][PATCH 10/17] tracepoint: Use __used attribute definitions from compiler_attributes.h
Date: Tue, 04 Aug 2020 16:57:53 -0400 [thread overview]
Message-ID: <20200804205813.348568049@goodmis.org> (raw)
In-Reply-To: 20200804205743.419135730@goodmis.org
From: Nick Desaulniers <ndesaulniers@google.com>
Just a small cleanup while I was touching this header.
compiler_attributes.h does feature detection of these __attributes__(())
and provides more concise ways to invoke them.
