| The access is already locked. And as the functions are only called

I didn't checked the precise code logic neither details, just wanted
to point out that 'wrapping' functions are beneficial sometimes (especially
when they hide details of internal data and provide some kind of interface
to play with). Dunno Joerg, I think it would be better to point out that
we want those functions being inlined by gcc 'inline' attribute explicitly.
But you choose :)
