Linux 4.12 Gained A Lot Of Weight: More Than One Million New Lines
With big merges this cycle from the DRM additions, a lot of new staging code, and more, the Linux 4.12 kernel is a bit heavier... Here's some numbers.
Curious how Linux 4.12 sizes in with the merge window closing this weekend and all major code pulled for it, here are some Git statistics I ran this morning on the tree for seeing how much 4.12 has grown over Linux 4.11.
When running cloc on the Linux Git tree this morning:
Or a total of 16.1 million detected lines of code, 3.2 million lines of comments, and 2.9 million blank lines spread in total across 48,753 files.
If looking at the churn over the past two weeks for the 4.12 merge window: 11870 files changed, 1323490 insertions(+), 298549 deletions(-). So over the past two weeks there have been 1.32 million lines of new code and 298k lines of deleted code, or a net gain of 1,024,941 lines.
In comparison, from v4.10 to v4.11-rc1 was: 11933 files changed, 524463 insertions(+), 239325 deletions(-). Or a net gain last merge window of just 285,138 lines. From v4.9 to v4.10-rc1 meanwhile was: 11468 files changed, 786937 insertions(+), 298643 deletions(-) or a net gain of 488,294 lines. So the amount of new code for Linux 4.12 is more than double the past two merge windows combined!
Long story short, Linux 4.12 will be a pretty big kernel! Stay tuned for my Linux 4.12 feature overview this weekend followed by various benchmarks once 4.12-rc1 has been released.
