Subject: [for-next][PATCH 01/15] tracing: Add printf attribute to log function
Date: Wed, 03 Feb 2021 11:05:18 -0500 [thread overview]
Message-ID: <20210203160548.763763707@goodmis.org> (raw)
In-Reply-To: 20210203160517.982448432@goodmis.org
From: Tom Rix <trix@redhat.com>
Attributing the function allows the compiler to more thoroughly
check the use of the function with -Wformat and similar flags.
