After changing the parameter from `NotSerialized` to `Serialized`, the
remark is indeed gone and there is no size change.
The remark was added in ACPICA version 20130517 [1] and gives the
following explanation.
If a thread blocks within the method for any reason, and another thread
enters the method, the method will fail because an attempt will be
made to create the same (named) object twice.
In this case, issue a remark that the method should be marked
serialized. ACPICA BZ 909.
