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

[Stephen Rothwell]

Hi Nick,

Today's linux-next merge of the vfs-scale tree got a conflict in
fs/9p/vfs_inode.c between commit 3d21652a1d23591e7f0bbbbedae29ce78c2c1113
("fs/9p: Move dotl inode operations into a seperate file") from the v9fs
tree and various commits from the vfs-scale tree.

I fixed it up by using the v9fs changes to that file and then applying
the following merge fixup patch (which I can carry as necessary).

Someone will need to fix this up before one of these trees is merged by
Linus, or to send this merge fix to Linus.
