     33  * Notes on porting:
     34  *
     35  * - Linux consistently passes around negative errno values.  NetBSD
     36  *   consistently passes around positive ones, except the special magic
     37  *   in-kernel ones (EJUSTRETURN, ERESTART, &c.) which should not be
     38  *   exposed to userland *or* linux-only code using the negative pointer
     39  *   means error return pattern.  Be careful!  If Using ERESTARTSYS from
     40  *   Linux code, be sure it is remapped back to ERESTART before NetBSD
     41  *   code sees it.
