From 1c569f0264ea629c10bbab471dd0626ce4d3f19f Mon Sep 17 00:00:00 2001 From: Josh Stone Date: Mon, 24 Aug 2009 14:43:14 -0700 Subject: tracing: Create generic syscall TRACE_EVENTs This converts the syscall_enter/exit tracepoints into TRACE_EVENTs, so you can have generic ftrace events that capture all system calls with arguments and return values. These generic events are also renamed to sys_enter/exit, so they're more closely aligned to the specific sys_enter_foo events.
