Not I. I'm totally comfortable with your decision, even though it seems
counter- to your own stated policy.

While I'm still unable to help noticing things, nobody seems to have
presented an argument that user-space and kernel-side will need to be
developed together. There's been an obvious assumption, with oprofile
given as that assumption's poster-boy, but why that should be the case
for tools/perf remains unclear. Probably the reasons are so obvious that
they go without saying, but as a disinterested observer, it seems to me
that in this case the two sides really are quite separate and
independent in a very real sense. Perhaps in the same sense that acct
and quota are.
