Pavel Safronov
Developed Linux memory management enhancements by introducing PR_SET_MEMORY_MERGE and PR_GET_MEMORY_MERGE constants in both the ferrocene/ferrocene and rust-lang/libc repositories. This work enabled per-process Kernel Same-page Merging (KSM) opt-in for Linux systems running kernel 6.4 or newer, aligning Linux memory-merge APIs with Android definitions to reduce API drift. Leveraged Rust for system programming and contributed to cross-repository collaboration, including cherry-picking changes across targets. Focused on improving memory efficiency for multi-process workloads, these enhancements utilized the Linux prctl API and advanced memory management techniques, delivering tangible improvements in memory utilization, performance potential, and developer experience without introducing new bugs.
