Yadan Fan

Worked on the geerlingguy/linux repository to enhance the stability of the kernel’s mempool subsystem, focusing on edge cases involving zero-minimum pools. Addressed a bug where threads waiting on memory were not properly awakened when memory was freed to an empty pool, and implemented safeguards in mempool_free to prevent crashes from invalid pointer dereferencing. Allocated at least one element for zero-minimum pools to ensure stable memory management and simplified the logic for adding elements. Delivered these improvements through two targeted commits using C, applying expertise in kernel development and memory management to improve reliability in low-memory scenarios without introducing new features.
