Does this block depend on unsigned long being 64-bit? Or should you
enforce it by using u64 that is always same sized unlike unsigned long?

Okay as unsigned long or do you want always 64-bit which is u64 ?
Define these inside the loops below and remove the types from the name.

Use the 64-bit divide from math64.h rather than leave it up to compiler.

You need to rework this to do 64-bit divide and remainder with

Is some *SEC_PER_*SEC define relevant for 1000 ?
Or some other units, e.g., HZ related?

Instead of _POS named variables, add GENMASK one instead and use
FIELD_PREP. You might need to use GENMASK_ULL() for the masks if you are
dealing with true 64-bitness here instead of the quasi unsigned longs.

GENMASK() + remove _POS define completely.

BIT() + remove _POS.
Is this really a mask or a bit? I'd remove _MSK from the name (which is
usually not that useful anyway even if it would be a multiple bit mask
for real).
