From ee364dcdcd008530883efc0e690fc8e85622f9b5 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 21 May 2019 16:51:08 -0300 Subject: perf trace beauty clone: Handle CLONE_PIDFD MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
