That part I don't understand: I can rename the function without making
it static and it builds fine, so where is it "tied" to the function
definition in kernel proper?

Don't get me wrong - leaking kernel proper symbols into the decompressor
has been a pet peeve of mine for a while now but this is not the case
here, is it?

And yes, the patch is fine - I'm just asking...

Thx.
