Hi Paul, Rafael, What happened to this in the end? I can't immediately find it on any of the pm git tree branches.

I thought that this would go in along with the other patches in the series. I can apply it directly, though, if needed. Thanks!

I think at this point Jonathan can just take it in his tree with his own patchset. Then I'll rebase this patchset on v6.1-rc1. Cheers, -Paul

Too late for me to take this for this cycle (I route via Greg KH so need to have things in place a little bit before the merge window). If Lee doesn't pick it up, I'll do an immutable branch after rc1 is out with just this patch on it, then anyone who wants it can pick it up. Thanks, Jonathan

Update the _EXPORT_DEV_PM_OPS() internal macro. It was not used anywhere outside pm.h and pm_runtime.h, so it is safe to update it. Before, this macro would take a few parameters to be used as sleep and runtime callbacks. This made it unsuitable to use with different callbacks, for instance the "noirq" ones. It is now semantically different: instead of creating a conditionally exported dev_pm_ops structure, it only contains part of the definition. This macro should however never be used directly (hence the trailing underscore). Instead, the following four macros are provided: - EXPORT_DEV_PM_OPS(name) - EXPORT_GPL_DEV_PM_OPS(name) - EXPORT_NS_DEV_PM_OPS(name, ns) - EXPORT_NS_GPL_DEV_PM_OPS(name, ns) For instance, it is now possible to conditionally export noirq suspend/resume PM functions like this: EXPORT_GPL_DEV_PM_OPS(foo_pm_ops) = { NOIRQ_SYSTEM_SLEEP_PM_OPS(suspend_fn, resume_fn) }; The existing helper macros EXPORT_*_SIMPLE_DEV_PM_OPS() and EXPORT_*_RUNTIME_DEV_PM_OPS() have been updated to use these new macros.
