While not an issue now, eventually we will have independent users of the extable.h file and we will stop sourcing it via module.h header. In testing that pending work, with very sparse builds, characteristic of an "allnoconfig" on various architectures, we can sometimes hit an instance where the very basic standard definitions aren't present, resulting in: include/linux/extable.h:26:9: error: 'NULL' undeclared (first use in this function) To be clear, this isn't a regression, since currently extable.h is only used by module.h -- however, we will need this addition present before we start migrating exception table users off module.h and onto extable.h during the next release cycle.
