I think we have to allow some testing before there could be claim that
there would be a major problem.

For instance these changes could go into linux-next until the 2.6.29
merge window .. Len should be back by then, and we should have a much
better idea what kind of problems may exist, if any..

It's all related .. I removed the semaphores in ACPI which are actually
mutexes in the first three patches. Your left with only semaphores that
are locked.. Locked semaphores are really completions, so it's natural
to convert them.

I would have liked to change the name in ACPI from "semaphore" to
"completion" , but you and Bob seemed to have some serious objections to
it, w.r.t other operating systems that are using that ACPI code.
