From: Paul E. McKenney
Date: Thu Aug 01 2019 - 18:43:15 EST


Hello!

This series provides enhancements to RCU pointer and list macros, all
courtesy of Joel Fernandes:

1. Rename rcu_dereference_raw_notrace() to _check().

2. Remove redundant debug_locks check in rcu_read_lock_sched_held().

3. Add support for consolidated-RCU reader checking.

4. Remove custom check for RCU readers.

5. Add lockdep condition to fix for_each_entry().

6. Convert to use built-in RCU list checking.

7. Pass lockdep condition to pcm_mmcfg_list iterator.

8. Use built-in RCU list checking for acpi_ioremaps list.

Thanx, Paul
