Hello linux community expert: >>I think this has been reported previously, and different patches have been proposed, have you searched the archives? > I haven't seen the patch given below before, I will read it carefully. > I searched for Linux mainline commits before submitting, but I only compared them according to the crash stack information and did not notice the following commit. I checked the stack trace again. The problem we encountered seems different from the problem reported in the link below, and they are not caused by the same reason. >>Specifically, take a look at: >>https://apc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Flore. >>kernel.org%2Fr%2F20240116141801.396398-1-khtsai%40google.com&data=05%7C >>02%7Chulianqin%40vivo.com%7Ca4b06e9db7bb43ab1bfc08dcbe01a836%7C923e42dc >>48d54cbeb5821a797a6412ed%7C0%7C0%7C638594161566475032%7CUnknown%7CTWFpb >>GZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0% >>3D%7C0%7C%7C%7C&sdata=pdb%2B1b1qB1q2%2BZN096D9jxNytfN7%2Fo50DPt6pq5m1RU >>%3D&reserved=0 Thanks
