This statement is false.

Care to check again with the mainline kernel? All the mainline
code was doing was incrementing these.

It may have regressed.  I 'know' it was correct in customer patched kernels as it fixed production stop bugs.

I 'believe' it was correct in mainline long back.  Perhaps it regressed during one of the refactoring passes.

It sounds like we have never had those pieces in the mainline
kernel though?

I don't think this is the case but maybe...  The code was perpetually broken in mainline for one reason or the other except for the most trivial case.

The mainline kernel PM code has been certainly working reliably
for me on omap3 for several years with off idle. That's how I
keep noticing various driver and PM regressions.

Customer phones did hang without a kick in production volumes for their use cases.

I will see if I can dig up an older image to cross check in the next few days...

OK thanks.

Tony
