Bug in ino_select() for machines where sizeof(int) != sizeof(long)

[Pete Delaney]

	There is a small bug in ino_select() for UNIX machines where the
sizeof(int) !=  sizeof(long).  The problem is that i_rd is declared as a
daddr_t and is cast to a dev_t throughout the kernel (yek!).  Anyway,
the code in sys_inode.c is missing the cast.
__________________________________________________________________________
				C O D E
ino_select(fp, which)
	struct file *fp;
	int which;
{
	register struct inode *ip = (struct inode *)fp->f_data;

	switch (ip->i_mode & IFMT) {

	default:
		return (1);		/* XXX */

	case IFCHR:
		return
#ifdef KEEP_4BSD_BUG
		    (*cdevsw[major(ip->i_rdev)].d_select)(ip->i_rdev, which);
#else
		    (*cdevsw[major(ip->i_rdev)].d_select)((dev_t)ip->i_rdev, which);
#endif
	}
}
