As pointed out by Krzysztof, this has user impact, so we have to weight
the benefit of this against the impact on those users.
As such, this needs a proper problem description
(https://docs.kernel.org/process/submitting-patches.html#describe-your-changes)
and are there are three (probably different) set of developers/users
impacted it would make sense to split it in three patches.

Bjorn
