We can do that in 64 bits easily. In 32 bits we'd only have 8 bits for unique inodes - no more than 256 keys on a volume. With 64 bit key_t's, we get up to 40 bits to lookup in the lookaside table - no worries :}. ftok() will have to become a cygdaemon wrapped function though - which IIRC it isn't today. So Chris: go ahead, but tell the cygwin ftok() maintainer when you do this. Oh, wait we don't have one just now. Sigh. I'll *try* to find time.
