Sometimes I also help to analyze and solve problems found by other departments on x86 servers, and contribute repair patches to the community. I sent you the almost same patch before (https://lore.kernel.org/all/20230110102745.2514694-1-zengheng4@huawei.com/), but you kept struggling with my grammar rather than the code logic itself, and even questioned my motives for sending the patch. (https://lore.kernel.org/all/Y7174pEWZ8IzCdQ9@zn.tnic/) Until just now, I saw your completely different responses to the same patch. I'm not pointing this out to change anything, but in the hope that other people or my colleagues would avoid encountering similar things. Regards, Zeng Heng
