No. It looks as if this, and also a number of comments in sys/ufs/ffs/fs.h and sys/ufs/ffs/ffs_alloc.c, are leftovers from the Olden Days. The value isn't used anywhere that I can see. Unless somebody can show that I'm wrong, I'd suggest that this is a documentation issue that I can take a look at. Greg -- Sent from my desktop computer. Finger [email protected] for PGP public key.
