From 24fa6c0832f4513ac897082d7d803970a40cc1b0 Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Sun, 6 May 2007 14:51:09 -0700 Subject: uml: move remaining useful contents of user_util.h Rescue the useful contents of the soon-to-be-gone user-util.h. pty.c now gets ptsname from stdlib.h like it should have always done. CATCH_EINTR is now in os.h, although perhaps all usage should be under os-Linux at some point. get_pty is also in os.h. This patch restores the old definition of ARRAY_SIZE in user.h. This file is included only in userspace files, so there will be no conflict with the kernel's new ARRAY_SIZE. The copy of the kernel's ARRAY_SIZE and associated infrastructure is now gone.
