Line-accurate confirmation: dirfs_mount calls vfs_getnewfsid (dirfs_vfsops.c:156) but every dirfs_statfs (:297-301) and dirfs_statvfs (:316-319) bcopy()s the entire HOST statfs/statvfs struct over sbp, replacing the unique fsid with the host filesystems - two dirfs mounts over the same host fs share an fsid and the mounts also misreport f_type/f_mntonname. Fix preserves mp->mnt_stat.f_fsid across the bcopy at both sites.",
