Subject: [PATCH v2 1/4] perf trace: substitute CAP_SYS_ADMIN with CAP_PERFMON in error message
Date: Wed, 22 Apr 2020 17:44:02 +0300	[thread overview]
Message-ID: <450d035a-c192-10e5-1c28-664ccae3e46e@linux.intel.com> (raw)
In-Reply-To: <66f2975b-4a69-b428-7dc5-d9aa40b3c673@linux.intel.com>


Update error message to mention CAP_PERFMON only. CAP_SYS_ADMIN still
works in keeping with user space backward compatibility approach.
