Subject: [git pull] vfs.git namespace stuff

	Rik's patches reducing the amount of synchronize_rcu() triggered
by ipc namespace destruction.  I've some pending stuff reducing that on
the normal umount side, but it's nowhere near ready and Rik's stuff shouldn't
be held back due to conflicts - I'll just redo the parts of my series that
stray into ipc/*.
