differences of array item types and the expression given to sizeof.
*) sequence to try coccinelle out on this case (when coccinelle installed):
$ wget http://coccinelle.lip6.fr/rules/array.cocci
$ sed 's/<linux\/kernel.h>/"lib.h"/' array.cocci > array-sparse.cocci
$ for i in $(find . -path ./validation -prune -o -name "*.c" -print); \
> do spatch -sp_file array-sparse.cocci $i; done
Beside proceeding messages, this will print out any "real" patch
generated according to the semantic patch in `array-sparse.cocci'
(it can also reflect these changes directly etc.).
