| * Pushed quiesce logic down into the task_finder layer.David Smith2008-08-292-46/+82

(utrace_derived_probe_group::emit_module_decls): Removed quiesce handler routines. Syscall probe handler detaches if systemtap state isn't correct. 2008-08-29 David Smith <dsmith@redhat.com> * task_finder.c (__stp_utrace_attach_match_filename): Don't call the callback when the interesting thread is found, call it when the tread is quiesced.
