Offering: HULK hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAX0HW

--------------------------------

The BTF information of the data structure in the kernel module is generated based on the corresponding kernel's base BTF when compiling the kernel module. When the kernel module is loaded into other kernels, unpredictable BTF verification errors will occur due to different base BTF, which will lead to the kernel module loading failed. Disable CONFIG_DEBUG_INFO_BTF_MODULES will skip the kernel module BTF verification.
