I need to add members to task_struct in Linux kernel 4.8.0. However, when I did it and tried to build the kernel, the error message shows:
In file included from linux-hwe-4.8.0/include/uapi/linux/stddef.h:1:0, from linux-hwe-4.8.0/include/linux/stddef.h:4, from linux-hwe-4.8.0/include/uapi/linux/posix_types.h:4, from linux-hwe-4.8.0/include/uapi/linux/types.h:13, from linux-hwe-4.8.0/include/linux/types.h:5, from linux-hwe-4.8.0/include/linux/compat.h:8, from linux-hwe-4.8.0/arch/x86/include/asm/fpu/internal.h:13, from linux-hwe-4.8.0/arch/x86/kernel/fpu/init.c:4: In function ‘fpu__init_task_struct_size', inlined from ‘fpu__init_system' at linux-hwe-4.8.0/arch/x86/kernel/fpu/init.c:390:2: linux-hwe-4.8.0/include/linux/compiler.h:491:38: error: call to ‘__compiletime_assert_192' declared with attribute error: BUILD_BUG_ON failed: sizeof(struct task_struct) != ALIGN(offsetofend(struct task_struct, thread), TYPE_ALIGN(struct task_struct)) _compiletime_assert(condition, msg, __compiletime_assert_, __LINE__)
How to get rid of such errors and build my kernel successfully?
