Subject: [PATCH 5/5] perf/core: Allow kernel address filter when not filtering the kernel
Date: Mon, 31 Jan 2022 09:24:53 +0200 [thread overview]
Message-ID: <20220131072453.2839535-6-adrian.hunter@intel.com> (raw)
In-Reply-To: <20220131072453.2839535-1-adrian.hunter@intel.com>
The so-called 'kernel' address filter can also be useful for filtering
fixed addresses in user space. Allow that.
