Filesystem drivers would use FUSE. A fairly long list of those is in the examples section of: http://en.wikipedia.org/wiki/Filesystem_in_Userspace Not all of those are Linux FUSE based, so don't assume they are all Linux filesystems, but many of them are. Note that a lot of filesystems that originate outside of linux, first come to linux as FUSE implementations. They may later be ported to native kernel modules. It is a effort vs. reward trade-off. I suspect the best known linux FUSE based filesystem is NTFS-3G. I've done some performance testing of it based on large files and USB3 connectivity. I don't see any meaningful performance degradation compared to EXT4 under the same restrictions.
