Worked on the geerlingguy/linux repository to enhance the maintainability of the Linux memory management subsystem, focusing on internal consistency and code clarity. The primary feature involved replacing direct printk logging with the pr_debug macro in numa_memblks.c, which standardized kernel log output and reduced unnecessary log noise. Additionally, memory size conversions in the NUMA and memblock subsystems were updated to use the SZ_1M macro, improving readability and ensuring consistent MB-level calculations. This work, implemented in C and leveraging skills in kernel development and memory management, laid a foundation for safer future modifications without introducing new bugs or regressions.
