This is not fair. And is not the proper working procedure. 
These problems existed before any BSD code. The BSD code did not add
anything to the mess.
If you want to fix the Linux code then it should be done separately,
by itself. In a different patchset. Which only fixes the Linux code.
This way if you have a regression you can go back to something that
worked before. Then if the Linux is fixed in a way compatible to BSD,
the compatibility layer can be removed by a latter patch.

Never MIX code changes with compatibility changes, because you cannot
separate the two if something goes wrong.

So what? Are you going to wait for all the Linux hacks and bugs fixed until
you put the BSD code? this is not the way to work!
