stable inclusion from stable-5.10.53 commit ff4b8f35c96c56a9029f58036e4f80eca59cddd0 bugzilla: 175574 https://gitee.com/openeuler/kernel/issues/I4DTUX Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=ff4b8f35c96c56a9029f58036e4f80eca59cddd0 -------------------------------- commit d952cfaf upstream. When a new CONFIG option is available, Kbuild shows a prompt to get the user input. $ make [ snip ] Core Scheduling for SMT (SCHED_CORE) [N/y/?] (NEW) This is the only interactive place in the build process. Commit 174a1dcc ("kbuild: sink stdout from cmd for silent build") suppressed Kconfig prompts as well because syncconfig is invoked by the 'cmd' macro. You cannot notice the fact that Kconfig is waiting for the user input. Use 'kecho' to show the equivalent short log without suppressing stdout from sub-make.
