The Kernel Put On Some Weight With Linux 4.13
Over the Linux 4.13 merge window, the kernel source tree managed by Git saw 10,000 files changed that amounted to 796,654 lines of code added and 205,239 lines of code deleted. Or in other words, a net gain in Linux 4.13 of 591,415. Here's the numbers compared to the past few merge windows:
v4.12 to v4.13-rc1: 10000 files changed, 796654 insertions(+), 205239 deletions(-)
v4.11 to v4.12-rc1: 11786 files changed, 1284429 insertions(+), 258856 deletions(-)
v4.10 to v4.11-rc1: 11906 files changed, 507714 insertions(+), 222576 deletions(-)
v4.9 to v4.10-rc1: 11318 files changed, 731816 insertions(+), 243522 deletions(-)
v4.8 to v4.9-rc1: 10511 files changed, 613258 insertions(+), 345895 deletions(-)
So the 4.13 merge window was decently sized, but not one of the biggest in recent times. What's more important than lines of code count is the features/changes and for that there are a lot of notable additions as outlined in our Linux 4.13 feature overview.
In terms of the overall size of the Linux kernel and related code including Kconfig and the few bundled user-space utilities, the Linux Git tree as of this morning checks in at 16,616,721 lines of code detected by CLOC. There are also another 3,269,464 lines of comments and 3,024,236 blank lines. The Git tree amounts to 49,132 files.
