Hi Masahiro!

Thanks for the v2. I've queued this up in the module tree with the
intention of getting the fixes in for -rc3.

Matthias is working on some modpost fixes that would get rid of the
__ksymtab_<symbol>.<ns>/__ksymtab_<ns>.<symbol> naming scheme
altogether in favor of just getting the namespace string from
__kstrtabns and __ksymtab_strings -- this may render patch 1
unnecessary. But since we want to fix this asap, we can just keep it
and apply Matthias's fix on top later.

Thanks!

Jessica
