hulk inclusion category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/ID9IFI ----------------------------------------- If CONFIG_XCU_SCHEDULER is not enabled, these two system calls sys_xsched_getattr and sys_xsched_setattr will not be defined, causing compilation errors. ld: vmlinux.o: in function `x64_sys_call': (.text+0x169b): undefined reference to `__x64_sys_xsched_getattr' ld: (.text+0x29f8): undefined reference to `__x64_sys_xsched_setattr' ld: vmlinux.o:(.rodata+0x1078): undefined reference to `__x64_sys_xsched_setattr' ld: vmlinux.o:(.rodata+0x1080): undefined reference to `__x64_sys_xsched_getattr' make[2]: *** [scripts/Makefile.vmlinux:37: vmlinux] Error 1 Therefore, it is necessary to add stub functions for these two system calls to avoid errors.
