[问题简述]
Anolis8.6 aarch64环境，libfuse-test测试，2022/10/26晚发起的nightly测试新增了test_ctests.pytest_notify_file_size[True]测试fail

[复现步骤]
git clone https://github.com/libfuse/libfuse.git
mkdir build
cd build
export PATH=/usr/local/bin/:$PATH
meson .. #yum install -y meson
ninja-build && ninja-build install
modprobe fuse && modprobe cuse # teardown: umount fusectl;modprobe -r cuse;modprobe -r fuse
python3 -m pytest test/

[期望结果]
用例pass

[实际结果]
