From f7e4217b007d1f73e7e3cf10ba4fea4a608c603f Mon Sep 17 00:00:00 2001 From: Roman Zippel Date: Wed, 9 May 2007 02:35:17 -0700 Subject: rename thread_info to stack This finally renames the thread_info field in task structure to stack, so that the assumptions about this field are gone and archs have more freedom about placing the thread_info structure. Nonbroken archs which have a proper thread pointer can do the access to both current thread and task structure via a single pointer. It'll allow for a few more cleanups of the fork code, from which e.g. ia64 could benefit.
