a23上面默认是fuse3，没有特殊情况不提供fuse2. 适配下用例看下。 -lfuse3试试
Anolis OS 23已经提供了fuse2，在编译环境上安装fuse2-devel试试。
在anolis23 x86 ECS环境下安装fuse2-devel后，kernel-selftests的memfd可以正常编译，问题解决 验证结果过程如下： ------------------ [root@qibo-anolis23-nightly-func-x86-1 BUILD]# cd kernel-5.10.134-61.git.3c4c5575a42e.an23/linux-5.10.134-61.git.3c4c5575a42e.a n23.x86_64/ [root@qibo-anolis23-nightly-func-x86-1 linux-5.10.134-61.git.3c4c5575a42e.an23.x86_64]# cd tools/testing/selftests/ [root@qibo-anolis23-nightly-func-x86-1 selftests]# cd memfd [root@qibo-anolis23-nightly-func-x86-1 memfd]# make gcc -D_FILE_OFFSET_BITS=64 -I../../../../include/uapi/ -I../../../../include/ -I../../../../usr/include/ memfd_test.c common .c -o /root/rpmbuild/BUILD/kernel-5.10.134-61.git.3c4c5575a42e.an23/linux-5.10.134-61.git.3c4c5575a42e.an23.x86_64/tools/testi ng/selftests/memfd/memfd_test memfd_test.c: In function 'mfd_assert_reopen_fd': memfd_test.c:64:14: warning: implicit declaration of function 'open'; did you mean 'popen'?
