Actually, you'll get a linker error if it's called with a 64-bit argument too. But your patch doesn't use __cmpxchg_u64 so it's fine. > Signed-off-by: Mathieu Desnoyers <[EMAIL PROTECTED]> Looks good to me. I suppose we _could_ implement 8- and 16-bit cmpxchg using stcond, but I really doubt it's worth it.
