Linux 7.3

Linux 7.3

Anyway, nothing very special seems to have happened this last week, so as expected the final 7.3 is out, and thus tomorrow the merge window for 7.4 opens. Except I’m on my annual family vacation, so instead of merging anything first thing in the morning, I’ll spend most of the day on a boat and under water. I’ll get back to merging in the afternoon, but I expect my schedule to be a bit unusual for a while.

无论如何,过去这一周似乎没发生什么特别的事情,所以正如预期的那样,7.3 正式版已经发布,因此 7.4 的合并窗口将于明天开启。不过我正在休年度家庭假,所以明天一早我不会进行任何合并工作,而是会花大部分时间在船上和水下。我会在下午恢复合并工作,但我预计我的日程安排在一段时间内会有些不同寻常。

This release is a record-breaker on all fronts; it brought in 18,765 non-merge commits from 3,021 developers, 807 of whom were first-time kernel developers.

此次发布在各方面都打破了记录;它引入了来自 3,021 名开发者的 18,765 次非合并提交,其中 807 名是首次参与内核开发的开发者。

Significant changes in this release include some significant binfmt_misc extensions, some group-scheduling work aimed at improving performance on large systems, the new failfs filesystem that fails all operations, the fchroot() system call, global per-CPU data for BPF programs, the completion of the sched_ext subscheduler feature, working-set tracking for virtual machines, alternative data-stream support in the ntfs3 filesystem, a long list of SMB server improvements, and much more. See the LWN merge-window summaries (part 1, part 2) and the KernelNewbies 7.3 page for details.

此版本的重要变更包括一些重大的 binfmt_misc 扩展、旨在提高大型系统性能的组调度工作、使所有操作均失败的新 failfs 文件系统、fchroot() 系统调用、用于 BPF 程序的全局每 CPU 数据、sched_ext 子调度器功能的完成、虚拟机工作集跟踪、ntfs3 文件系统中的替代数据流支持、一长串 SMB 服务器改进等等。详情请参阅 LWN 合并窗口摘要(第 1 部分,第 2 部分)和 KernelNewbies 7.3 页面。

For consuming kernel features from userspace, there is the The Linux Programming Interface (thick) book, but the latest edition dates back from 2010; thankfully there is a page listing what’s new since then.

对于从用户空间使用内核功能,有一本《Linux 系统编程》(厚书),但最新版本还是 2010 年的;好在有一个页面列出了自那以后的新变化。

For an introductory book/documentation about Linux kernel development itself, what would you recommend nowadays? I know there is Linux Device Drivers, but it becomes a bit old I suppose.

对于 Linux 内核开发本身的入门书籍/文档,你们现在有什么推荐吗?我知道有《Linux 设备驱动程序》,但我猜它已经有点过时了。

What resources would you recommend nowadays? (It’s just for my own curiosity, but answering the question could help other readers).

你们现在推荐什么资源?(这只是出于我个人的好奇,但回答这个问题可能会帮助其他读者)。

I believe one recommended stating point is https://kernelnewbies.org/.

我相信一个推荐的起点是 https://kernelnewbies.org/。

So before the Linux merge window, there’s the Linus submerge window. (I’ll get my coat!)

所以,在 Linux 合并窗口之前,还有 Linus 的“潜水”(submerge)窗口。(我这就去拿外套走人!)
