As today is the last day of 2023, I checked some open source commits statistics using my simple and buggy script, and github. Similar statistics for 2022 is available at another post.
In short, I made 8th and 4th biggest changes to Linux kernel memory management subsystem among the 295 people, for lines of changes (1,910) and commits (66).
For the Linux kernel whole tree, the numbers become 264th (3,562 lines) and 80th (147 commits) among 5,006 people.
As today is the last day of 2022, I checked some open source commits statistics using my simple and buggy script[1], and github.
Linux kernel statistics I ran my buggy script[1] to show some 2022 statistics for memory management subsystem and whole tree of Linux kernel as below.
Memory Management In 2022, 305 people participated in Linux kernel memory management subsystem development by making 81,631 lines of changes with 2,135 commits.
A summary of DAMON development in 2022 has posted: https://lore.kernel.org/damon/20221229171209.162356-1-sj@kernel.org/
2022 was a year of active and healthy DAMON development.
Seven new DAMON major features were delivered to users. Some of those were featured in articles and academic papers.
It was possible thanks to the DAMON community. The community has expanded with its own mailing list and an open bi-weekly chat series. 40 people contributed their great code to DAMON via making their 275 commits merged into the mainline.
Whenever reading the kernel development statistics report for each release from LWN, I wanted to scope it down to specific subsystems. For that, I wrote a script.
Belows are the top 10 kernel hackers who contributed to the memory management subsystem of Linux kernel, sorted by number of commits and changed (added, deleted, or modified) lines, respectively.
