The f9 kernels have an intermediate state of the utrace code (newish API but before utrace_engine_get and many other various changes/fixes). I had been keeping thoughts of f9 and backports blissfully absent from my conscious mind for quite some time. Basically I still am. The Fedora (10) rawhide kernels have the latest bleeding-edge utrace code from my tree and stay current on a daily basis. If you can use those for now, that is certainly simplest. I think it will work fine on an f9 userland. I'd been expecting that 2.6.27 might be cut real soon already, and then hoping for new f9 update kernels to be based on that. Since everything short of utrace proper (and some self-contained arch bits) got merged for 2.6.27, it's the first version where "backporting" will be a real breeze for me. I realize it's a bit of hassle for systemtap hackers running stable Fedora. But for the moment I still don't think my top priorities should include 2.6.26 backport of the current work. If too much longer goes by before 2.6.27 and/or there is huge demand for it, maybe I will have to do it. Thanks, Roland
