[GIT PULL] 9p updates for 4.19

[Dominique Martinet <asmadeus@codewreck.org>]

Hi Linus,

9p has seen some recent surge of activity recently and I've stepped up
to help maintaining 9p; please let me know if there are things to
improve in how I do things.
In particular, the gpg key I used to sign the tag is getting rather old
(1024 bit dsa is considered weak nowadays) and I will have a newer key
ready for 4.20, but I didn't think I would be able to gather signatures
for 4.19 so went for this one for now. Sorry for that.

I've rebased the branch at the start of the week to add some stable Cc
but all the patches have been in linux-next for two weeks, and all
transports have been tested since the rebase (thanks to Stefano
Stabellini for xen!)


The following changes since commit 94710cac0ef4ee177a63b5227664b38c95bbf703:
