Hi,

> ./arch/x86/include/asm/uaccess.h: In function ‘set_fs’:
> ./arch/x86/include/asm/uaccess.h:31:9: error: dereferencing pointer to
> incomplete type

I can reproduce your problem by including <asm/uaccess.h>, but not with 
<linux/uaccess.h>.

	#include <asm/uaccess.h>
	//#include <linux/uaccess.h> does compile
	#include <linux/module.h>


	int __init init(void)
	{
		set_fs(get_fs());
		return 0;
	}

	void __exit finit(void)
	{
	}

	module_init(init);
	module_exit(finit);

If my memory is any good, direct inclusion of <asm/uaccess.h> was 
deprecated in 4.12 and new code should use <linux/uaccess.h>

Thanks,
Seraphime Kirkovski
