I have the impression that the code in kernel/power/process.c was
compiled only if CONFIG_PM_SLEEP was set. Now that the code has been
moved to kernel/freezer.c, it is unconditionnaly compiled in every
kernel. Is that correct ?

If so, is it possible to put this new feature under some
CONFIG_SOMETHING option, for people who care about the kernel size ?

Thanks,

Thomas
