Trouble is, it's exported as a shared library in the xfslibs-dev package
(should that be libxfs-dev?) so depending on how conservative you like
to be we can't just rip it out.
(Though I suppose even Linus has occasionally allowed people to rip and
replace kernel/user ABIs when they can demonstrate that it was so broken
it never worked for anybody, ever. :P)

Yeah, this patch was quite quick and dirty when I wrote it, on the
assumption that tons of other stuff was going to need reorganization by
the time there was a need to land this.
