Is it necessary for CONFIG_PAGE_POOL_STATS to be enabled by default in Arch Linux 2023.08.01?

Hello, I recently noticed that in Arch Linux 2023.08.01, CONFIG_PAGE_POOL_STATS=y. As we know, this option incurs additional CPU and memory cost. In addition to enabling this option, these statistics are only available if the driver using the page pool supports exporting this data. Does enabling this configuration by default have any performance impact? Is it necessary to enable it by default? Thank you for your time. ------------------------------ Institute of Software Chinese Academy of Sciences Intelligent Software Research Center Mail:sunying@isrc.iscas.ac.cn Web: https://isrc.iscas.ac.cn/
