Bug Description

In our Artful kernel SRU test pool, this test will only failed on two nodes: "pepe"(Dell PowerEdge R310) and "daedalus"(Intel Purley 2S)

Steps:
  1. git clone --depth=1 https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/artful linux
  2. cd linux
  3. git checkout -f
  4. git clean -f -d
  5. git ls-files --others --directory
  6. xargs rm -rvf
  7. rm -rf '.git/rebase*'
  8. git fetch origin master
  9. git reset --hard FETCH_HEAD
  10. patch -p1
  11. cd tools/testing/selftests
  12. make clean
  13. make
  14. sudo bpf/test_maps

Result:
* The test failed with the "Cannot allocate memory" error message:
