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.
