chars in a path name including nul */

stap is working for more than this number. In the following command I given
'130000' also, it just giving those many no.of characters in the help. 

# b=`perl -e 'print "A"x100'`; stap -I$b
A script must be specified.

Usage: stap [options] FILE         Run script in file.
   or: stap [options] -            Run script on stdin.
   or: stap [options] -e SCRIPT    Run given script.

Options:
   --         no more options after this
   -v         increase verbosity [0]
   -h         show help
   -V         show version
   -k         keep temporary directory
   -u         unoptimized translation
   -g         guru mode
   -P         prologue-searching for function probes
   -b         bulk (percpu file) mode
   -s NUM     buffer size in megabytes, instead of 0
   -p NUM     stop after pass NUM 1-5, instead of 5
              (parse, elaborate, translate, compile, run)
   -I DIR     look in DIR for additional .stp script files, in addition to
              /usr/share/systemtap/tapset
              /usr/share/systemtap/tapset/LKET
             
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
   -D NM=VAL  emit macro definition into generated C code
   -R DIR     look in DIR for runtime, instead of
              /usr/share/systemtap/runtime
   -r RELEASE cross-compile to kernel RELEASE, instead of 2.6.18-36.el5
   -m MODULE  set probe module name, instead of stap_30031
   -o FILE    send output to file, instead of stdout
   -c CMD     start the probes, run CMD, and exit when it finishes
   -x PID     sets target() to PID
   -t         collect probe timing information
   -q         generate information on tapset coverage
#
#  b=`perl -e 'print "A"x65000'`; stap -I$b -R$b

The same case with -R also if you are using both -I and -R at max you can give
till 65000 and in the case of just -I can give till 130000. Thanks!!
