summary
Covers proposed Linux-kernel changes to FUSE that let filesystems bypass the userspace daemon for local data transfers to avoid extra kernel↔userspace copies, improving performance to be comparable with native kernel filesystems. Also explains a generic file-descriptor storage mechanism to enable userspace FUSE daemons to perform hot upgrades and emergency failover, increasing reliability.
