Subject: [PATCH 20/44] perf trace beauty clone: Handle CLONE_PIDFD
Date: Mon, 27 May 2019 19:37:06 -0300 [thread overview]
Message-ID: <20190527223730.11474-21-acme@kernel.org> (raw)
In-Reply-To: <20190527223730.11474-1-acme@kernel.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
In addition to the older flags. This will allow something like this to
be implemented in 'perf trace"
perf trace -e clone/PIDFD in flags/
I.e. ask for strace like tracing, system wide, looking for 'clone'
syscalls that have the CLONE_PIDFD bit set in the 'flags' arg.
For now we'll just see PIDFD if it is set in the 'flags' arg.
