Re: [PATCH openEuler-1.0-LTS 0/6] Fix the problem that the number of tcp timeout retransmissions is lost

 hi qiulaibin:

      该问题的主要修复补丁是补丁集中的第６个补丁，对应commitId: 3256a2d6ab1f71f9a1bd2d7f6f18eb8108c48d17 其它几个补丁被依赖或间接依赖，２、３补丁是为修复第１个补丁引入的，这３个补丁可以都不合，４和５都是一些函数的变形或提炼， 未有大的改动，之前提意见使用patchset合入的原因就是为了保持与开源代码一致性，如果要最小的改动解决问题，提交 https://mailweb.openeuler.org/hyperkitty/list/kernel@openeuler.org/message/O... 满足要求，请评审使用哪种方式合入。

祝：工作愉快

hi zhenyuan:

针对你先前提交的“Fix the problem that the number of tcp timeout retransmissions is lost”补丁集，我们在内部review的时候committer给了如下 检视意见

切换EDT主线有 tcp 和 fq 的几个patchset和bugfix, 这里建议先合入解决本问题 后边的3个patch。

因此是否只合后三个patch就可以满足能够解决你目前遇到的问题。
