Why do we need to export the no_hash_pointers variable and not declare it in any header file?
Because lib/test_printf.c wants to use no_hash_pointers for testing purpose, and lib/test_printf.c might be built as a loadable kernel module. That is, no_hash_pointers is not meant for general use. config TEST_PRINTF tristate "Test printf() family of functions at runtime" obj-$(CONFIG_TEST_PRINTF) += test_printf.o
