Well, for 2.6.22, Kprobes will just be disabled if you use DEBUG_RODATA.
And yes, that patch already got merged. However, the patch to *allow*
Kprobes with DEBUG_RODATA is not, and will not be. It's not a regression,
and quite frankly, I don't think I would even want that patch.
Kprobes fundamntally disagrees with DEBUG_RODATA, there's no point in
"working around it". Better just admit it.

It depends on the purpose of DEBUG_RODATA. If DEBUG_RODATA was for
security reasons then I agree, but it seems to be more to catch
accidental writes. Kprobes isn't an accidental write and I would
suspect many developers would want to catch accidental writes and be
able to insert kprobes.
Or is there something else I'm missing - i.e. you're saying the patch
itself is crap?
