Adrian Hunter 5b427df27b perf kcore_copy: Do not check /proc/modules is unchanged ... /proc/kallsyms and /proc/modules are compared before and after the copy in order to ensure no changes during the copy. However /proc/modules also might change due to reference counts changing even though that does not make any difference. Any modules loaded or unloaded should be visible in changes to kallsyms, so it is not necessary to check /proc/modules also anyway. Remove the comparison checking that /proc/modules is unchanged.
