From 07354a00901d103085e4376b7df0aad264c1836a Mon Sep 17 00:00:00 2001 From: "Adam B. Jerome" Date: Wed, 6 Dec 2006 20:35:30 -0800 Subject: [PATCH] [PATCH] /proc/kallsyms reports lower-case types for some non-exported symbols This patch addresses incorrect symbol type information reported through /proc/kallsyms. A lowercase character should designate the symbol as local (or non-exported). An uppercase character should designate the symbol as global (or external). Without this patch, some non-exported symbols are incorrectly assigned an upper-case designation in /proc/kallsyms. This patch corrects this condition by converting non-exported symbols types to lower case when appropriate and eliminates the superfluous upcase_if_global function Signed-off-by: Adam B.
