From: Michael Jeanson Date: Thu, 1 Apr 2021 18:39:01 +0000 (-0400) Subject: cleanup: explicitly mark unused parameters (-Wunused-parameter) X-Git-Tag: v0.13.0~20 X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=70469b43316ecc8d6053550504858ad8a8ef9b16;p=userspace-rcu.git cleanup: explicitly mark unused parameters (-Wunused-parameter) Add the 'unused' attribute to function parameters that are unused to allow turning on -Wunused-parameter and distinguish unused parameters that are actual errors.
