Subject: [PATCH v2 4/7] perf tools: Move clockid_res_ns under clock struct
Date: Wed,  5 Aug 2020 11:34:41 +0200	[thread overview]
Message-ID: <20200805093444.314999-5-jolsa@kernel.org> (raw)
In-Reply-To: <20200805093444.314999-1-jolsa@kernel.org>

Moving clockid_res_ns under clock struct, so we have
clock related stuff in one place.
