[PATCH -rcu v2 0/2] kcsan: Improvements to reporting

[Marco Elver]

Improvements to KCSAN data race reporting:
1. Show if access is marked (*_ONCE, atomic, etc.).
2. Rate limit reporting to avoid spamming console.

v2:
* Paul E. McKenney: commit message reword.
* Use jiffies instead of ktime -- we want to avoid calling into any
  further complex libraries, since KCSAN may also detect data races in
  them, and as a result potentially leading to observing corrupt state
  (e.g. here, observing corrupt ktime_t value).


Marco Elver (2):
  kcsan: Show full access type in report
  kcsan: Rate-limit reporting per data races
