Subject: [PATCH] perf parse-events: Set exclude_guest for user-space counting
Date:   Wed, 12 Aug 2020 14:59:53 +0800
Message-Id: <20200812065953.22143-1-yao.jin@linux.intel.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Currently if we run 'perf record -e cycles:u', exclude_guest is 0.

But it doesn't make sense that we request for user-space counting
but we also get the guest report.

To keep perf semantics consistent and clear, this patch sets
exclude_guest for user-space counting.
