objtool reports the following new warning: kernel/exit.o: warning: objtool: do_exit() falls through to next function complete_and_exit() The warning is caused by do_exit()'s new call to do_task_dead(), which is a new "noreturn" function which objtool doesn't know about yet, introduced by: 9af6528e ("sched/core: Optimize __schedule()") ( objtool has to know all the global noreturn functions so it can follow the control flow of any functions which call them. Unfortunately they need to be hard-coded because there's no automated way to detect them. ) Reported-by:
