struct hrtimer_clock_base *base
1091  move hrtimer, called with base lock held
1093  如果mode按位与 Time value is relative to now则tim等于Add two ktime values and do a safety check for overflow:
1096  tim等于hrtimer_update_lowres(timer, tim, mode)
1098  hrtimer_set_expires_range_ns(timer, tim, delta_ns)
1101  new_base等于switch_hrtimer_base(timer, base, mode & Timer is bound to CPU (is only considered)
1103  返回:queue_hrtimer - internal function to (re)start a timer* The timer is inserted in expiry order. Insertion into the* red black tree is O(log(n)). Must hold the base lock.* Returns 1 when the new timer is the leftmost timer in the tree.
