Hi Murphy

Test 13) still passes on my environment. mke2fs and mkfs.xfs version should not affetc all filesystem results, I think them can be excluded.
I update my gcc version to 8.3.1 20190507 ,glibc updates to  glibc-2.28-66.el8.x86_64(I don't have glibc-2.28-72.el8.x86_64, if you failed
on both glibc and syscall, I think this fail is no related with glibc).

Can you print more informatin when you run this case, as below:
