Abstract
An augmented sleepable read-copy update implementation (PREEMPT_SRCU) combines elements of a tree-based sleepable read-copy update environment (Tree-SRCU) with elements of a preemptible read-copy update environment (Preemptible-RCU). The elements of Tree-SRCU may be used to manage PREEMPT_SRCU grace periods and handle PREEMPT_SRCU callbacks. The elements of Preemptible-RCU may be used to drive existing PREEMPT_SRCU grace periods to completion.
