Of course, if you're feeling adventurous and willing to at least entertain the
mere speculation of switching the kernel source to C++, we could then use
inline template functions:
template <typename T>
static inline T __READ_ONCE(T &var)
{
T val = *(const volatile T *)&var;
return val;
}
template <typename T>
static inline T READ_ONCE(T &var)
{
T val;
compiletime_assert_rwonce_type(var);
val = __READ_ONCE(var);
smp_read_barrier_depends();
return val;
}
Of course, that would mean using C++...
