Folks,

this is the follow up to the "vfs.git pile 3 - dcache" pull request [0].
It was concluded that the introduction of
	preempt_disable_nested()

in general makes sense and should be used in places where preemption on
!RT is disabled by other means and PREEMPT_RT need to explicitly disable
it.

This series introduces the macro and converts already existing users to
that macro. The u64_stat interface was simplified to make the change
simpler and code easier to follow.

Thanks. Apart from 1/9 where I had just that "this visually looks odd
and threw me" comment, this all looks like good nice cleanups to me.
