So, test filled filesystem and fallocate() succeeded anyway.

This looks like test issue. systemd on Fedora31 started using cgroup2 exclusively:
  cgroup2 on /sys/fs/cgroup type cgroup2 (rw,nosuid,nodev,noexec,relatime,seclabel,nsdelegate)

Tests are trying to mount single hierarchy on cgroup1:
[pid 283933] 04:57:26 mkdir("/dev/cgroup", 0777) = 0
[pid 283933] 04:57:26 mount("memcg", "/dev/cgroup", "cgroup", 0, "memory") = -1 EBUSY (Device or resource busy)
