| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | document signal syscall hookiddefs.stp: some changes to the hookid: Now the hookid of a return type event(addevent.*.return) should be an even number and its value should be the corresponding entry event hookid +1. The hookid of a non-return type event should be an odd number. Add the hookid of HOOKID_REGEVTDESC register_event.stp: add register_evt_desc() to register the description of an event. Change the register_sys_event() to add the an argument representing event description Allow to use empty format string and empty field name when calling register_event(). Change all calling to register_sys_event() to add an argument which represents the event description. Change register_evt_desc() and register_event() to add an argument representing the event description string, which could help facilitate the error debugging. iosyscall.stp: bugfix to add the variable GroupID and hookID nfs.stp: bugfix to add some omitted probe definitions. nfs_proc.stp: bugfix of the wrong calling to _lket_trace() for nfs_proc.remove.entry.
