This series provides updates for polled SRCU grace periods, mainly for Tiny SRCU: 1. Make "srcud" option also test polled grace-period API. 2. Add GP and maximum requested GP to Tiny SRCU rcutorture output. 3. Make Tiny SRCU poll_state_synchronize_srcu() more precise. 4. Make Tiny SRCU use full-sized grace-period counters.
