When eBPF Meets FUSE - Improving Performance of User File Systems

Explore the intersection of eBPF and FUSE technologies in this conference talk from the Linux Plumbers Conference. Delve into the performance improvements achievable for user file systems by combining these two powerful tools. Learn about the differences between kernel and user file systems, understand the basics of File Systems in User Space (FUSE), and discover various FUSE optimizations. Gain insights into eBPF's overview and practical examples before diving into the ExtFUSE architecture, its implementation, and performance benefits. Examine real-world applications of ExtFUSE and get updated on the project's current status. This talk, presented by Ashish Bijlani from Georgia Institute of Technology, offers valuable knowledge for developers and system administrators looking to enhance file system performance in user space.
