Looking into it in a bit more depth, I can probe vfs.read on my Fedora
box at home, but it fails on the Ubuntu box I have to use at work.
Probing on the kernel vfs_read() directly works. The Ubuntu vfs.stp
is significantly shorter than the Fedora one, and in particular, lacks
the probes for vfs.{read,write}
So the simple question is, can I just copy over the updated vfs tapset?
The work server is Ubuntu 8.04 and comes with a relatively archaic
systemtap-0.0.20071201-1. Is there anything in the newer tapsets that
would fail to work with a systemtap that old?
(Incidentally, stap-report isn't present either)
