Sorry for may not be related question in this thread.


         xtime.tv_nsec = (INITIAL_JIFFIES % HZ) * (NSEC_PER_SEC / HZ);

#include <stdio.h>

#define HZ 1000
#define NSEC_PER_SEC (1000000000L)
#define INITIAL_JIFFIES ((unsigned long)(unsigned int) (-300*HZ))

int main()
{
	printf("%ld\n", (INITIAL_JIFFIES % HZ) * (NSEC_PER_SEC / HZ));
	return 0;
}

hirofumi@devron (a)[1006]$ ./c
296000000

xtime.tv_nsec was not 0. Is this bug?
