But if we disable CONFIG_KEXEC_AUTO_RESERVE, that means crashkernel=auto will be invalid, this is the same as it is now.Ok, but since 'crashkernel=auto' is not used today, nobody has 'crashkernel=auto' in the bootloader configuration. So I don't see any practial advantage of that config option. Eric, what's your opinion on that, do we need a config option CONFIG_KEXEC_AUTO_RESERVE or could we just implement that feature unconditionally (if CONFIG_KEXEC is enabled, of course).The only reason I can see the option going away would be a dependency on CONFIG_HOTPLUG_MEM.
I am not sure if I understand you correctly, but it doesn't and won't depend on CONFIG_MEMORY_HOTPLUG.
