rhel4u2 kernel experiences


Hi -

The tentative RHEL4U2 kernel (2.6.9-16.EL) running on FC3, with
hand-recompiled elfutils-113 .src.rpm and a hand-compiled systemtap
CVS, shows the best test results and functionality I've seen yet.

On the down side, return probes seem fragile.  For example,
running this script:
    probe kernel.function("sys_read") { log ("a") }
    probe kernel.function("sys_read").return { log ("b") }
results in 128 "a" messages, and countless "b" ones.
