LINUX KERNEL --
With all the new features in Linux 4.9, obviously Tux put on a bit of weight this kernel cycle... Here's some numbers.

In yesterday's Linux 4.9 feature overview I failed to mention the latest code stats for this exciting kernel update that's introducing Greybus, boasts experimental GCN 1.0 AMDGPU support, supports 29 new ARM machines, and much more.

Between Linux 4.8 and 4.9-rc1 there were 10746 files changed, 695693 insertions(+), and 428330 deletions(-). In other words, a net gain of 267,363 lines (including code, documentation, Kconfig, etc).

While Linux 4.9 packs in many exciting changes, going from Linux 4.7 to Linux 4.8 yielded: 11486 files changed, 662979 insertions(+), and 314598 deletions(-). Or with v4.6 to v4.7 it was lighter: 9910 files changed, 576071 insertions(+), 277560 deletions(-).

Running cloc on the latest Linux Git tree, it's up to 45,727 files. There are 14,864,279 detected lines of kernel code, 2,982,891 lines of comments, and 2,793,211 blank lines.

Obviously the vast majority of the Linux kernel is C code/headers followed by Assembly.

Well, that's the latest number fun for the Linux 4.9 Git state.
