gcc 版本过低，在展开asm_inline时出错，应该如gcc 9，保持与内核编译环境一致：
cat /proc/version:
Linux version 5.4.204-1.el7.elrepo.x86_64 (mockbuild@Build64R7) (gcc version 9.3.1 20200408 (Red Hat 9.3.1-2) (GCC)) #1 SMP Tue Jul 5 16:32:13 EDT 2022

CentOS上更换编译链：
yum --enablerepo=extras install centos-release-scl-rh
yum install devtoolset-9-gcc
scl enable devtoolset-9 bash

已编译成功，感谢~
