rcu: introduce rcu_defer_qs_clear() helper

Browse source

Currently rdp->defer_qs_pending transitions from DEFER_QS_PENDING to
DEFER_QS_IDLE at two sites: rcu_preempt_deferred_qs_irqrestore() and
rcu_preempt_deferred_qs_handler() (depth>0 reset).  Both write the
IDLE value directly.

Introduce a single inline helper rcu_defer_qs_clear() in tree.h and
route both sites through it.  This becomes the single
PENDING->IDLE transition point for upcoming work.
