Thanks for rebasing -- I haven't forgotten, just been otherwise busy.

Will make time for this and the netfs rework over the next couple of
weeks.


Just a couple of notes:

linux-fsdevel@...r is still not in Cc of the patches, and they weren't
for any other version except for one of my replies, so it might be worth
resending just for them as it touches do_mounts.c / root_dev.h

I don't think it's worth adding yourself as MAINTAINERS for this, will
likely strip it out (I know I'm the one who asked for your help if
people have problems with this, but we should keep contacts simple)
I'll forward you requests when they come if it's not trivial and you're
not subscribed to the v9fs-developer@sf list
