From 730760e90a173ef81f89beed2f1dad2fab310f68 Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Fri, 29 Sep 2006 01:58:50 -0700 Subject: [PATCH] uml: locking documentation Some locking documentation and a cleanup. uml_exitcode is copied into a local before sprintf sees it, in case sprintf does anything non-atomic with it. The rest are comments about why certain globals don't need any kind of locking.
