Okay, Thank you.
BTW, I am impressed with the NO (noticeable) overhead added
by having systemtap probes. Of course, I wasn't really doing
a performance measurement. I was doing untars, kernel compiles
with probes in add_to_page_cache() and remove_from_page() -
which gets called a lot and didn't make much difference in the
kernel compile time :)
time with probe:
(Totals PageAdd = 215326 PageDel = 17612)
real 3m40.492s
user 5m44.894s
sys 1m2.276s
time without probe:
real 3m40.085s
user 5m45.650s
sys 1m1.572s
Thanks,
Badari
