Abstract:
A technique for motivating lazy RCU callbacks under out-of-memory conditions. In response to detecting an actual or potential OOM condition, non-lazy callback processing is performed for all processors whose RCU callback lists are non-empty due to at least one callback permitting lazy callback processing being present.
