The performance gains achieved by these patches are significant. In tests using a build that included all modules—referred to as “allmodconfig”—the compilation speed increased by about 36 percent. Even more significant improvements were observed in incremental builds, where the speed increased by about 70 percent.

The project is led by Lorenzo Stoakes of ARM, who recently submitted the second revision of the patches. While two of the original patches have already been integrated into the upstream code, the remaining v2 patches include several updates. These include rebasing the code against the latest upstream Linux Git repository and the option to disable the parallel frontend for the Rust compiler.

If the remaining patches are accepted, these optimizations are expected to be integrated into the Linux 7.4 kernel cycle. The updates will result in a noticeable increase in the efficiency of the build pipeline for developers and system administrators.
