Motivating lazy RCU callbacks under out-of-memory conditions |
| 摘要 |
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. |

1. In a computing system having one or more processors operatively coupled to one or more memory devices, a method for motivating lazy read-copy update (RCU) callbacks under out-of-memory (OOM) conditions, the method comprising:
detecting an actual or potential OOM condition; and performing non-lazy callback processing for all processors whose RCU callback lists are non-empty due to at least one callback permitting lazy callback processing being present. |
