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.

Make all integers passed into _lket_trace() casted into int64_t explicitly.
Delete calling to filter_by_pid()

document nfs trace hooks
tapset/nfsd.stp, tapset/nfs_proc.stp, tapset/nfs.stp:
Change NFS file identifier. Change NFS version data type
from String to INT. Add version variable to nfs_open
and nfs_release.
LKET/iosyscall.stp:
change log_iosyscall_sync() be sync with different timing methods.
LKET/utils.stp:
add reset_maxaction() since there are too many functions called inside "probe begin".
LKET/nfsd.stp, LKET/nfs_proc.stp, LKET/nfs.stp:
New trace hooks for NFS, including both NFS client and server side activities.
LKET/register_event.stp:
Add the register event calls for NFS trace hooks.

sub-hooks for each iosyscall.
make update_record() work for ascii tracing
|

delete filter_by_pid filter for io scheduler event hooks
|
|
|
the io syscall hook differs with syscall hook since it will
provide all the available info of function parameters instead
of logging only the syscall name. Useful to trace the detail
behavour of io related syscalls
