Linux 5.1 Should Be Released Today With IO_uring, Faster zRAM, More Icelake
Barring any last minute regrets causing Linus to opt for a 5.1-rc8 test release, Linux 5.1.0 will be out today. Last week Torvalds indicated he was feeling like the release should be ready this weekend as opposed to kicking in an extra RC.
For those that don't recall all of the changes of this next stable kernel, see our Linux 5.1 feature overview. The work exciting us the most is Intel Fastboot being enabled by default for newer hardware, various security improvements, the ability to use persistent memory as system RAM, IO_uring is quite interesting for faster and more efficient I/O, Intel 22260 WiFi support, Raspberry Pi 3 Model A+ mainline kernel support, continuing to square away Icelake hardware support, and a lot of smaller changes.
Stay tuned this evening to see if Linux 5.1 successfully makes it out, which will mark the opening of the Linux 5.2 merge window. Linux 5.2 is looking to be even bigger and one of the biggest feature updates to this open-source kernel in a while.
For those wondering about the size of Linux 5.1, here is the cloc output as of 5.1 Git this morning... 17.8 million lines of code, 3.3 million lines of comments, and 3.2 million blank lines.
