I think 6.9 added passthrough support. Are you using that? Also, FOPEN_CACHE_DIR is default when there is no fuse-server open method defined - does your implementation have an open/dir_open? I think the only user of FOPEN_CACHE_DIR is in fs/fuse/readdir.c and that always checks if it is set - either the flag gets set or does not come into role at all, because passthrough is used?
