Dear list,
the system tap examples include a page fault counter. However, I've
noticed that it's way off with the number of page faults it records. A
simple
# stap -c df pfaults.stp
records about 20 page faults (minor and major). A simple cross-check with
# \time df
shows that it should report ~270 page faults.
What am I missing?!
Thanks,
Thomas.
