VFAT patent avoidance and patent workarounds

Well, we've already seen "don't discuss details of the implementation of
this patch: $PERSON will send you a private email explaining the design"
(and then he apparently doesn't, at least not yet) which means that if
this patch goes in we have opaque design decisions in the kernel for the
sake of a single (large) country's appalling legal regime. Great stuff.

I wonder what can't-discuss-it code will be going in for the Chinese
government next? They're hot on Linux and China has a much bigger
population than the US.
