UBUNTU: SAUCE: (no-up) trace: add trace events for open(), exec() and uselib()
BugLink: http://bugs.launchpad.net/bugs/462111
This patch uses TRACE_EVENT to add tracepoints for the open(),
exec() and uselib() syscalls so that ureadahead can cheaply trace
the boot sequence to determine what to read to speed up the next.
It's not upstream because it will need to be rebased onto the syscall
trace events whenever that gets merged, and is a stop-gap.
