From ef5f88c3578682534931b6958f99bdc1a6a33869 Mon Sep 17 00:00:00 2001 From: kib Date: Sun, 5 Jun 2016 17:04:03 +0000 Subject: Get rid of struct proc p_sched and struct thread td_sched pointers. p_sched is unused. The struct td_sched is always co-allocated with the struct thread, except for the thread0. Avoid useless indirection, instead calculate td_sched location using simple pointer arithmetic in td_get_sched(9). For thread0, which is statically allocated, create a structure to emulate layout of the dynamic allocation.
