Subject: [PATCH 13/30] perf report: Ignore kptr_restrict when not sampling the kernel
Date: Tue, 28 Nov 2017 12:02:03 -0300 [thread overview]
Message-ID: <20171128150220.5064-14-acme@kernel.org> (raw)
In-Reply-To: <20171128150220.5064-1-acme@kernel.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
If none of the evsels has attr.exclude_kernel set to zero, no kernel
samples, so no point in warning the user about problems in processing
kernel samples, as there will be none.
