Also, if you're adding AFTER_FREEZE, it would be good to add BEFORE_THAW too
for symmetry.

But there is no use case for BEFORE_THAW. At least it is not needed for now.

For your use case, a single function pointer would be sufficient too.

What do you mean by single function pointer? kernel/power is part of
kernel image and dm-crypt is external kernel module.

Well, if there is a function pointer in the core suspend code initially set to
NULL and exported to modules such that the dm-crypt code can set it to
something else, that should be sufficient, shouldn't it?

So if you're adding new PM notifier events, that's already more than *you* need.

Anyway, I guess the "post freeze" new one should be enough for now, but please
change the name to POST_FREEZE.

Also I think we don't need separate "post freeze" events for suspend and
hibernation.

Thanks,
Rafael
