From: Florian Westphal <fw@xxxxxxxxx>
Stephen Rothwell says:
today's linux-next build (x86_64 allmodconfig) produced this warning:
./usr/include/linux/netfilter/nf_osf.h:25: found __[us]{8,16,32,64} type without #include <linux/types.h>
Fix that up and also move kernel-private struct out of uapi (it was not
exposed in any released kernel version).
tested via allmodconfig build + make headers_check.
Reported-by: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>
Fixes: bfb15f2a95cb ("netfilter: extract Passive OS fingerprint infrastructure from xt_osf")
