Linux 4.5 Released – Main Changes, ARM and MIPS Architectures

Linus Torvalds released Linux Kernel 4.5 on Sunday:

So this is later on a Sunday than my usual schedule, because I just couldn’t make up my mind whether I should do another rc8 or not, and kept just waffling about it. In the end, I obviously decided not to,but it could have gone either way.

We did have one nasty regression that got fixed yesterday, and the networking pull early in the week was larger than I would have wished for. But the block  layer should be all good now, and David went through all his networking commits an extra time just to make me feel comfy about it, so in the end I didn’t see any point to making the release cycle any longer than usual.

And on the whole, everything here is pretty small. The diffstat looks a bit larger for an xfs fix, because that fix has three cleanup refactoring patches that precedes it. And there’s a access type pattern fix in the sound layer that generated lots of noise, but is all very simple in the end.

In addition to the above, there’s random small fixes all over-shortlog appended for people who want to skim the details as usual.

Go test, and obviously with 4.5 released, I’ll start the merge window for 4.6.

Linux 4.4 added support for a faster and leaner loop device, 3D support in virtual GPU driver, TCP improvements, various file systems improvements for BTRFS, EXT-4, CIFS, XFS etc… Some notable changes made to Linux 4.5 include:

Some new features and improvements specific to the ARM architecture:

MIPS changes:

If you want to get the full details, I’ve generated Linux 4.5 Changelog with comments only (12.2MB) using git log v4.4..v4.5 --stat, but it’s probably a better idea to simply check out Linux 4.5 changelog on kernelnewbies.org.
