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