Subject: [PATCH] sched/cputime: Mark function as __maybe_unused
Date: Tue, 18 Aug 2020 18:03:36 +0100 [thread overview]
Message-ID: <20200818170337.805624-1-alex.dewar90@gmail.com> (raw)
Depending on config options, account_other_time() may not be called
anywhere. Add __maybe_unused flag to fix clang warning.
