From de5fe76e436d9e98f8af8005ff23a2e6066aea10 Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Sat, 10 Feb 2007 01:44:25 -0800 Subject: [PATCH] [PATCH] uml: umid tidying Add an error message when two umids are put on the command line. umid.h is kind of pointless since it only declares one thing, and that is already declared in os.h. Commented the lack of locking of some data in os-Linux/umid.h.
