Which means you can't actually have a filesystem of more than 2^24-1
blocks.
From:

They're 24 bits, aren't they?
Not according to the source:
typedef long daddr_t;
daddr_t s_fsize; /* size in blocks of entire volume */
short s_nfree; /* number of addresses in s_free */
daddr_t s_free[NICFREE];/* free block list */
(from param.h and filsys.h respectively).
