tracing: Kill "filter_string" arg of replace_preds()
Cosmetic, but replace_preds() doesn't need/use "char *filter_string". Remove it to microsimplify the code. Link: http://lkml.kernel.org/p/20140715184832.GA20519@redhat.com Signed-off-by: Oleg Nesterov <oleg@redhat.com> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
