I built and installed 2.6.20.7.
Testsuite all runs fine except current.stp which dies on this:
semantic error: no match for probe point while resolving probe point
kernel.function("*@kernel/sched.c").call
Changing that to kernel.function("*").call, I see lots on enabled probes in sched.c

The issue here is that the compilation unit name "kernel/sched.c"
pattern does not match the full path compiled on your tree. Plus
our globbing function does not permit full-path patterns like
"**/kernel/sched.c". It's not obvious what to do here.

I wonder how common this is. I expect if I had built in my source tree instead
of into a separate object directory things would work normally. I will try that.
