Subject: linux-next: manual merge of the vfs tree with the v9fs tree

Hi Al,

Today's linux-next merge of the vfs tree got a conflict in
net/9p/protocol.c between commit 6250a8badb31 ("9p: use unsigned
integers for nwqid/count") from the v9fs tree and commit 3f39ef33084b
("net/9p: switch the guts of p9_client_{read,write}() to iov_iter")
from the vfs tree.

I fixed it up (I think - see below) and can carry the fix as necessary
(no action is required).

Cheers,
