[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.
