[PATCH v2 0/4] RCU fixes for rcu_assign_pointer() usage

From: Joel Fernandes (Google)
Date: Wed Mar 20 2019 - 20:34:53 EST


This is just a resend with scheduler patches split from the driver fixes and
Paul's Reviewed-by(s) added.

These patches fix various sparse errors ccaused as a result of the recent check
to add rcu_check_sparse() to rcu_assign_pointer(). The errors are due to
missing annotations. The annotations added in the series can also help avoid
future incorrect usages and bugs so it is a good idea to do in any case.

RFC v1 -> Patch v2:
Made changes based on Peter Zijlstra review.

Joel Fernandes (Google) (4):
sched/cpufreq: Annotate cpufreq_update_util_data pointer with __rcu
sched_domain: Annotate RCU pointers properly
rcuwait: Annotate task_struct with __rcu
sched: Annotate perf_domain pointer with __rcu
