Well, you would have to do something about this bit of code:
/* include/linux/pagemap.h */ static inline unsigned long _page_hashfn(struct inode * inode, unsigned long offset) { #define i (((unsigned long) inode)/(sizeof(struct inode) & ~ (sizeof(struct inode) - 1))) #define o (offset >> PAGE_SHIFT) #define s(x) ((x)+((x)>>PAGE_HASH_BITS)) return s(i+o) & (PAGE_HASH_SIZE-1); #undef i #undef o #undef s } Michael Chastain <mailto:mec@shout.net> "love without fear"
