* ialloc.c (diskfs_free_node): Use %Ld format for ino_t/off_t values.
* pager.c (diskfs_grow, pager_unlock_page): Likewise.
* inode.c (read_node): Likewise.
* dir.c (diskfs_get_directs): Likewise.
* dir.c (diskfs_direnter_hard): Use size_t for OLDSIZE.
Fail with EOVERFLOW when it would exceed that width.
