Linux 4.14 Is Up To Around 23.2 Million Lines Of Code
While I usually look at the Linux kernel code size following each merge window, I am a few days late this time around due to busy Xeon/EPYC benchmarking and XDC2017. Anyhow, Linux 4.14 is showing some weight gains but nothing too bad.
Linux 4.14 has been another busy cycle with a lot of happenings from finally seeing Heterogeneous Memory Management merged to a lot of other new core functionality plus the always fun and exciting changes and new support happening in driver space. See our Linux 4.14 feature overview for a rundown on the new functionality.
As of Linux 4.14 Git today just prior to the 4.14-rc2 tagging, the overall kernel size comes in at a total of 23,265,768 lines spread among 49,802 files. The 23.2 million lines amount to about 16.87 million lines of detected code, 3.31 million lines of comments, and about 3.07 million blank lines. Here is the CLOC output from the Linux Git tree as of this morning:
In terms of how much was gained during the Linux 4.14 merge window, between 4.13 stable and 4.14-rc1 it saw 11,547 files changed yielding 586,300 insertions and 335,089 deletions. It's not that bad considering the amount of feature work packed into this release. From 4.12 to 4.13-rc1 meanwhile was 10,000 files changed with 796,654 insertions and 205,239 deletions. Or from 4.11 to 4.12-rc1 was 1,284,429 insertions and 258,856 deletions. So the 4.14 size increase isn't all that bad considering all that's taken place this cycle.
Stay tuned for continuing Linux 4.14 kernel benchmarks shortly on Phoronix.
