So will an inline like this work?
static inline void *__user convert_user_ptr(uint64_t ioctl_ptr)
{
#ifdef CONFIG_COMPAT
if (is_compat_task())
return compat_ptr((compat_uptr_t)ioctl_ptr);
else
#endif
return (void __user *)(unsigned long)ioctl_ptr;
}
then I can convert all the code to just use that instead of explicity
casts or brokenness.
Dave.
