I test this case on centos8.2, it failed, but it passed on centos7.8 and 
fedora31. On upstream kernel (5.9-rc7+,commit 6f2f486d57c4,using kvm,4G 
memory,2 cpus), it also failed. I don't know whether it has some kernel 
parameters or kconfig to affect this. It seems not a kernel bug and like 
a environment bug(I guess).
