Subject: [PATCH 06/44] perf trace: Use perf_evsel__sc_tp_{uint,ptr} for "id"/"args" handling syscalls:* events
Date: Thu, 9 Aug 2018 11:57:44 -0300 [thread overview]
Message-ID: <20180809145822.21391-7-acme@kernel.org> (raw)
In-Reply-To: <20180809145822.21391-1-acme@kernel.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
Now it looks just about the same as for the trace__sys_{enter,exit}.
