[PATCH 01/33] misc: adapt tests to handle the fuse ext[234] drivers

Darrick J. Wong
2025-10-29T01:20:42Z

It would be useful to be able to run fstests against the userspace
ext[234] driver program fuse2fs. A convention (at least on Debian)
seems to be to install fuse drivers as /sbin/mount.fuse.XXX so that
users can run "mount -t fuse.XXX" to start a fuse driver for a
disk-based filesystem type XXX.

Therefore, we'll adopt the practice of setting FSTYP=fuse.ext4 to
test ext4 with fuse2fs. Change all the library code as needed to handle
this new type alongside all the existing ext[234] checks, which seems a
little cleaner than FSTYP=fuse FUSE_SUBTYPE=ext4, which also would
require even more treewide cleanups to work properly because most
fstests code switches on $FSTYP alone.
