## 环境信息 【内核版本】kernel-4.19，kernel-5.10，kernel-6.6 ## 缺陷信息 【实际结果】 在配置静态大页场景下，带外方式触发page soft offline流程下线1个page，会直接下线大页的内存空间（如：2M、1G）； 【期望结果】 1. 在配置静态大页场景下，带外方式触发page soft offline流程下线1个page，默认不处理该流程，除非用户显性配置需要响应该流程； 2. 在配置4K页面或者透明大页场景下，带外方式触发page soft offline流程下线1个page，默认响应该流程执行下线操作。 **二、缺陷分析结构反馈** 影响性分析说明： 缺陷严重等级:(Critical/High/Moderate/Low) 缺陷根因说明: 受影响版本排查(受影响/不受影响): openEuler-20.03-LTS-SP4 openEuler-22.03-LTS-SP3 openEuler-22.03-LTS-SP4 openEuler-24.03-LTS openEuler-24.03-LTS-SP1 openEuler-24.03-LTS-SP2 修复是否涉及abi变化(是/否): openEuler-20.03-LTS-SP4 openEuler-22.03-LTS-SP3 openEuler-22.03-LTS-SP4 openEuler-24.03-LTS openEuler-24.03-LTS-SP1 openEuler-24.03-LTS-SP2
