Paul E. McKenney 9a0c6fef42 rcu: Make RCU_FAST_NO_HZ handle adaptive ticks ... The current implementation of RCU_FAST_NO_HZ tries reasonably hard to rid the current CPU of RCU callbacks. This is appropriate when the CPU is entering idle, where it doesn't have much useful to do anyway, but is most definitely not what you want when transitioning to user-mode execution. This commit therefore detects the adaptive-tick case, and refrains from burning CPU time getting rid of RCU callbacks in that case. Signed-off-by: Paul E.
