Improve FUSE Filesystem Performance and Reliability

Explore the latest improvements in FUSE (Filesystem in UserSpacE) performance and reliability in this 26-minute conference talk by Tao Peng from Ant Group. Dive into the challenges posed by FUSE's user-kernel space separation design and learn about innovative solutions being discussed in the Linux kernel community. Discover how bypassing the userspace daemon for local data transmission can significantly enhance FUSE filesystem performance, making it comparable to native kernel filesystems. Examine the introduction of generic file descriptor storage and its role in enabling hot-upgrades and panic-failovers for FUSE userspace daemons. Gain insights into FUSE architecture, FD passthrough metrics, fallback mechanisms, and core data structures. Understand the potential for FUSE daemon reliability improvements and explore future developments in this critical area of filesystem technology.
