My specific issue is with FUSE_EXT_OWNER_UID_GID, which I think is unnecessary. Just fill the header with the mapped uid/gid values, which most servers already use for creating the file with the correct st_uid/st_gid and not for checking permission. When the mapped values are unavailable, set the uid/gid in the header -1. Should be better than sending nonsense values to userspace, no? Thanks, Miklos
