there are numerous places throughout the source tree that apparently
calculate the size of an array using the construct
"sizeof(fubar)/sizeof(fubar[0])". see for yourself:

$ grep -Er "sizeof\((.*)\) ?/ ?sizeof\(\1\[0\]\)" *

but we already have, from "include/linux/kernel.h":

#define ARRAY_SIZE(x) (sizeof(x) / sizeof((x)[0]))

Maybe *(x) instead of (x)[0]?
