This helper seems unrelated to the patch subject and should be done
separately.
more specifically - you have created the helper BUT you have not used
it at ALL places where we update BAT. That is seriously wrong from the
code completness POW. If you have getter - you MUST use it everywhere,
even within allocate_clusters().
Normally you create helper, f.e. refactoring code of allocate cluster
promising
that the code will be reused later (non-functional changes) and after that
in the separate patch you spread its usage refactoring other code, f.e.
to avoid flush_bat tracking.
