Now that the code has been +AD4 moved to kernel/freezer.c, it is unconditionnaly compiled in every +AD4 kernel. Is that correct ? +AD4 +AD4 If so, is it possible to put this new feature under some +AD4 CONFIG+AF8-SOMETHING option, for people who care about the kernel size ? How about making it depend on a combination of CONFIG variables? Here's an RFC PATCH. Completely untested.
