This looks like an error in include/linux/types.h.  The aligned types should 
probably not be defined inside #ifdef __KERNEL__.

The following other headers expose aligned 64-bit types to user space as well; 
copying the netfilter list:

	include/linux/if_ppp.h
	include/linux/netfilter/nfnetlink_queue.h
	include/linux/netfilter/nfnetlink_log.h
	include/linux/netfilter/xt_quota.h
	include/linux/netfilter/xt_connbytes.h

Otherwise, the definition of those types is really simple, and this would do 
in include/linux/fanotify.h until include/linux/types.h is fixed:

	#ifndef aligned_u64
	# define aligned_u64 __u64 __attribute__((aligned(8)))
	#endif

Thanks,
Andreas
