I'm not really doubting what you claim, Jan, but it would be really
helpful if you provided some data to support the proposed change
(Kernel source references, or notes about testing you've done, or 
pointers to mailing list threads, authoritative note that you are
the maintainer of some relevant kernel subsystem...). Do you have
something like that? (It's also useful for the change log.)

Thanks,

Michael
