It breaks the ia64 build:
ima_fs_cleanup: discarded in section `.exit.text' from security/built-in.o
it's calling an __exit function from a non-_-exit function.
I'll remove the __exit tag from ima_fs_cleanup(), but that's the wrong fix - really the caller should be fixed but it's all tangled up in a quite unnecessary inlined function.
I must say that this code doesn't leave an impression of having sufficient overall quality. It needs some caring for. - 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/
