Subject: cleanup: explicitly mark unused parameters (-Wunused-parameter)
X-Git-Tag: v2.13.0-rc1~158
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=2208d8b5689264e35ed0a660d8c3c82021cc0367;p=lttng-ust.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.
