I'm not sure how to reply to his patch series directly since I'm not
subscribed to lkml
(I imagine I can set headers manually, such that things get
appropriately threaded,
but for now let me just reply here). I don't think there's much to it.
It seems like any
use of `current_text_addr()` in `ARCH=um` build will cause this
problem, there's just
not very many such uses in the code base. I believe this particular
problem should
be reproducible as long as CONFIG_INET is set for an `ARCH=um` build.
