Yup, 11 has been unsupported/broken for over a year, now; I was trying to
get an OpenAFS 1.8 out before this became a serious issue, but it seems
that is not in the cards.

It is as-yet unknown how much work getting things patched up will be, at
least as far as I know.  I am pretty sure I started looking at it at some
point, but don't remember exactly where that would be (not that I remember
having gotten very far).  IIRC, there was one use of b_saveaddr for which
it was not immediately clear what the proper fix was, but I do not expect
it to require a big restructuring, just some research.  Of course, they
may be further issues lingering, and there is the potential for runtime
issues as well.
