Linux 4.18-rc1 Kernel Released
Linus Torvalds decided to cut the 4.18-rc1 release one day ahead of the normal two-week long merge window, thereby also marking the end to new feature work to be merged for Linux 4.18.
Linus Torvalds closed the merge window early since he's currently in Japan and will be on a boat / scuba diving on Sunday. He wrote of 4.18-rc1, "this release looks fairly regular - both in size and in behavior. We actually have managed to shrink things a bit more this release too, as people have clearly gotten excited about the whole 'let's remove old unused code'. It's not nearly as noticeable as it was for 4.17, but rc1 has actually caused a bit of shrinkage:"
Linux 4.18 is another exciting cycle with a lot of graphics driver improvements, excitement on the I/O front, and some more controversial work like merging Fscrypt Speck support and dropping the Lustre file-system from mainline.
My original feature overview on the prominent Linux 4.18 kernel changes will be up shortly and our usual kernel benchmarks coming up soon.
When running some stats on the Linux Git tree as of this Saturday night, from v4.17 to v4.18-rc1 there are 12479 files changed, 560339 insertions(+), 667549 deletions(-). So the Linux 4.18 kernel at this stage is about 107k lines of code lighter, thanks to the removal of Lustre and other clean-ups particularly in the staging area.
Lastly, some numbers when running CLOC on the Git tree as of 4.18-rc1 for some code statistics:
