It's a name that seems like it should be a straightforward
cast of a kernel pointer to a __user pointer like:
=20
static inline void __user *to_user_ptr(void *p)
{
=A0=A0=A0=A0=A0=A0=A0=A0return (void __user *)p;
}

ahh, ok.=A0=A0I guess I was used to using it in the context of ioctl
structs..=A0=A0in that context u64 -> (void __user *) made more sense.
=20
Maybe uapi_to_ptr()?=A0=A0(ok, not super-creative.. maybe someone has a
better idea)

=20
Maybe u64_to_user_ptr?

That is a good name. If everyone agrees I can resend this patch
changing it to u64_to_user_ptr. Then should we still keep it on
kernel.h?
