[git pull] vboxsf

[Al Viro]

vboxsf, with fixups for fs_parse changes folded in.  Identical to what
had been in -next - git diff work.vboxsf merge.nfs-fs_parse comes empty.
It is a rebase (on top of merge.nfs-fs_parse.1), but it's a single commit
and here the tree being identical to what had been tested is all that
matters - feeding it in two chunks (original commit + fixups) would be
completely pointless, IMO.  That should be it for bisect hazards from
fs_parse API changes...
