TheLinux Torvalds, boss of the inux, released the stable version of the Linux 5.1 kernel after seven candidates for release. Kernel versions usually reach stable status after seven or eight candidate versions. It is therefore preferable that Linux 5.1 takes shape a week earlier. In addition, the code name "Shy Crocodile" of the latest version remains identical to that of previous versions.
Compared to other versions, Linux 5.1 arrived a little late in the day due to last minute extraction requests. In his announcement message, Linus wrote that the requests "not big enough to justify delaying things, and I hope the timing of the merge window will not be so painful either."
According to Phoronix, Linux 5.1 includes about 17.8 million lines of code and 3.3 million comment lines; it comes with many new features.
Now let's move on to major changes. Here are a few:
New features of Linux 5.1
The new high performance I / O interface is the strong point of Linux 5.1. the new interface io_uring should bring fast, scalable asynchronous I / O to Linux. In addition, it also adds a user space library that allows applications to configure an io_uring instance without needing to know the ins and outs of io_uring.
This version also iEnhances the fanotify interface this helps a Linux file system monitor changes and adds the "super-root monitoring" feature as a scalable way to track changes.
Another important change in Linux 5.1 is the support for the use of persistent memory in RAM. It has already been clearly established in the past that this could lead to some compromises in performance, but it is good to see that Linux gives the choice to let users use NVDIMMs as additional RAM.
With version 5.1, the Linux kernel also continues to run on problem of the year 2038. Other major features include new material support, Main R-Pi 3 model A + core support, Intel 22260 WiFi support, etc.
As I already mentioned, the Linux 5.1 kernel contains many new features; if you want to dive deeper, I suggest you read this article on Kernel Newbies.
The latest version was not available on kernel.org at the time of writing, but should be available soon.
