★ 维护者解释「回滚 fair 调度策略」

dri-devel · drm-sched · PATCH v3 00/19

英文原段 There was a late minute user regression report, so let's revert this so it can be debugged in peace. I have not been able to locally reproduce it yet, but at least a partial fix looks to be this. Further debug will be needed, possibly after the holiday/vacation season is over.
中文理解 「最后关头冒出一个用户回归报告，所以咱们先回滚，好让问题能安安静静地调试。我本地还没能复现它，但至少部分修复看起来是这个。进一步调试还需要，可能要等假期/休假季过去。」
阅读要点 late minute user regression = 临门一脚的用户回归；debugged in peace = 安安静静调试（in peace 语气）；locally reproduce = 本地复现（内核 bug 报告高频）；holiday/vacation season = 维护者的时间表达

★ 两个值得记的表达

dri-devel · 讨论

debugged in peace 「安安静静地调试」——in peace 表「不受打扰」；revert so it can be debugged in peace = 回滚是为了能专心调试
I have not been able to ... yet 「我还没能……」——yet 结尾表“到目前还没”，维护者说明复现困难的礼貌说法

✍️ 阅读理解：用英文回答两个问题——① 为什么维护者要回滚 fair 调度策略？② 他是否已复现问题、打算怎么继续？
💡 显示答案
参考：① Because a late minute user regression report came in, so he reverted the policy switch to debug it in peace. ② He has not been able to reproduce it locally yet, and further debug will be needed, possibly after the holiday season.

📎 原文引用

A late minute regression → revert → debug in peace. Reading LKML is reading how maintainers think.
