Linux Kernel At 19.5 Million Lines Of Code, Continues Rising

With Linux 4.1 having been released this week and being mid-way through 2015, here's some Git development statistics for the newest kernel code.

On Sunday I ran GitStats against the latest Linux kernel code. The last time I had done this was at the start of the year when recapping 2014 for the Linux kernel and at that time the kernel source tree was at 19.1 million lines. As of this weekend just prior to the Linux 4.2 merge window opening, the Git code-base was over 19.5 million lines -- or another 400k+ lines so far this year.

GitStats showed 19,509,218 lines of code across 520,260 commits from 13,708 authors. There's 49,457 files currently part of the kernel source tree.

Linus Torvalds remains the "author of the month" for most months but other prolific contributors continue to be Takashi Iwai, David Airlie, David Miller, Al Viro, and others.

Those wishing to dig through these latest Linux kernel development stats can find the GitStats output via this directory.
