| |
Hello!
This series contains SRCU updates:
1. Fix kernel-doc missing notation, courtesy of Randy Dunlap.
2. Prevent __call_srcu() counter wrap with read-side critical section.
3. Lock srcu_data structure in srcu_gp_start(), fixing a an extremely rare but also extremely embarrassing concurrency bug, courtesy of Dennis Krein.
4. Use "ssp" instead of "sp" for srcu_struct pointer, in the hope that this prevents confusion about which lock is held.
Thanx, Paul
