Well TBH there's a lot of accumulated stuff including some treewide cleanups in my fstests branch that needs to go upstream before the fuse2fs changes. I've been waiting the entire year to see if check-parallel will get finished... and I'm not going to wait anymore. That's why I haven't tidied up this patchset at all. The TLDR version is that FSTYP=fuse.ext4 is how you select the fuse server, and you ought to have mkfs.fuse.ext4/fsck.fuse.ext4 point to the appropriate e2fsprogs programs; a [fuse.ext4] section in mke2fs.conf; and fuse4fs installed as /sbin/mount.fuse.ext4 or /sbin/ext4 depending on how your libfuse is configured. Then this series is basically making sure that FSTYP=fuse.ext* works, and turning off feature tests for things that aren't supported by fuse2fs. --D
