/* In theory BFS supports up to 512 inodes, numbered from 2 (for /) up to 513 inclusive.
In actual fact, attempting to create the 512th inode (i.e. inode No. 513 or file No. 511)
will fail with ENOSPC in bfs_add_entry(): the root directory cannot contain so many entries, counting '..'.
So, mkfs.bfs(8) should really limit its -N option to 511 and not 512. For now, we just print a warning
if a filesystem is mounted with such "impossible to fill up" number of inodes */
