Thus this text in memory will be freed in future. Once we add the "__init" preceding function name, we can use following command to find it in specfied section. $ objdump -t -j .init.text built-in.o built-in.o: file format elf64-x86-64 SYMBOL TABLE: 0000000000000000 l d .init.text 0000000000000000 .init.text 0000000000000000 l F .init.text 000000000000004e klp_init Signed-off-by: Minfei Huang --- kernel/livepatch/core.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/kernel/livepatch/core.c b/kernel/livepatch/core.c index 284e269..86e40b9 100644 --- a/kernel/livepatch/core.c +++ b/kernel/livepatch/core.c @@ -973,7 +973,7 @@ static struct notifier_block klp_module_nb = { .priority = INT_MIN+1, /* called late but before ftrace notifier */ }; -static int klp_init(void) +static int __init klp_init(void) { int ret; -- 2.2.2 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
