[klibc] [BUG][PATCH] fstype: wrong size returned for jfs

Hi guys,

I've noticed that the size returned by the fstype utility was
not correct for JFS filesystems (it returns the size in number
of HW blocks instead of bytes).

Here is a simple patch that addresses it (based on 1.5.7 from
the debian package).

 	}
 	return 0;

HTH,
