Okay, that's fine.

Of course.

Okay, I will send all the fixes that you can apply cleanly now in a
separate set.

So, yeah, I get your overall concern. What about this:
- A single patchset to make sure the current policy->freq_table is
always sorted in Ascending order of frequencies.
- And this sorting will be done per policy only when the policy is
first created.
- Which would eventually mean merging this series with the [v2 0/2]
one.

Will that work ?
