| |
Hello!
This series parallelizes grace-period initialization for expedited grace periods and adds a couple of fixes:
1. Parallelize expedited grace-period initialization in order to reduce the growth of latency with increasing numbers of CPUs.
2. Updates comments on which locks are to be held to match the code, courtesy of Boqun Feng.
3. Protect all calls to sync_rcu_preempt_exp_done() with the corresponding rcu_node structure's ->lock held, courtesy of Boqun Feng.
Thanx, Paul
