Guys, what blocksize are you using? BTW, old testcase was
cat >foo.c <<EOF
#include <unistd.h>
main(argc,argv)
int argc;
char **argv;
{
	int fd;
	char c=0;
	truncate(argv[1], 10);
	fd = open(argv[1], 1);
	lseek(fd, 16384, 0);
	write(fd, &c, 1);
	close(fd);
}
EOF
gcc foo.c
./a.out /tmp/something_old
od -c </tmp/something_old
where something_old would be something not touched for long (i.e.
completely out of cache). Buggy kernels would leave much more than
10 non-zero bytes. Correct result is a file with bytes 11-16385 being zero.
I doubt that it would be the same beast, though...
