[RFC][PATCH 0/4] Another go at ktime_get_raw_fast_ns()

[Peter Zijlstra]

Hi John,

So yeah, I just didn't try hard enough it seems; how about this?

Also, I think we should double check that everything passed to
tk_setup_internals(.clock) is either static storage or RCU-sched freed,
because with the whole latch thing one CPUs (fast) access might still be
in progress while the other is freeing the clock struct.

Not sure what the lifetime rules of struct clocksource are here.
