The fact that direct_io kind of works leads me to think this a problem
with fuse, and not gvfs. Gvfs will simply call fuse_main() with the
arguments passed to it. It's up to the fuse userland and kernel module
to provide a lot of the heavy lifting. To that end, you might try
rebuilding your kernel module, or ask the fuse maintainer if they have
