Hello, I have a few questions about the padata code I've been studying recently: - Why does padata use the WQ_UNBOUND attribute of the workqueue? Because I've noticed a significant maintenance cost related to CPUs. Are there any specific benefits? - In what scenarios is it necessary to specify a CPU for serial execution, or is ensuring the order sufficient? In fact, the two questions can be summarized into one: Is it possible to avoid handling CPU-related operations to simplify the code logic? Thanks.
