Worked on the PhotonLibOS repository to enhance the FUSE adaptor, focusing on stability and performance for long-running workloads. Addressed memory leaks by implementing centralized IdentityPool-based memory management for fuse_buf allocations and frees, ensuring compatibility with libfuse3 and improving maintainability. Developed the fuse_handle class to robustly manage session resources across both high-level and low-level FUSE operations. Introduced splice I/O support to the request receive path, optimizing data transfer efficiency with force_splice_read and rewriting interfaces to align with the libfuse low-level API. Utilized C++ and system programming skills, emphasizing memory management, file systems, and I/O optimization throughout the work.
