From 6dcbd212ff4988d8e6caa0b6700bd1c1d317dc02 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 21 Aug 2018 11:40:09 -0300 Subject: [PATCH] perf trace: Extract the comm/tid printing for syscall enter Will be used with augmented syscalls, where we haven't transitioned completely to combining sys_enter_FOO with sys_exit_FOO, so we'll go as far as having it similar to the end result, strace like, as possible.
