-EXPORT_SYMBOL(__kasan_kmalloc); Sorry, but this will break all users of kmalloc() with KASAN on if !TRACING:*module users. An allmodconfig but with CONFIG_TRACING=n will probably show you the problem.Follow your advice, I changed CONFIG_TRACING=n in .config. Then I run "make -jxx modules". But CONFIG_TRACING is changed to y. So what you mentioned does not appear.
CONFIG_TRACING is not user selectable but auto-selected, just have to disable all those that select it. See .config, which breaks.
