Kernel 4.11.0-1014.14 azure
This test has failed on all the azure instances this cycle, it looks like it has stopped at the "rename-empty-dir" test:

 TEST rename-file.py:110: Rename file over a dir
 ./run --rename /mnt/a/foo108/ /mnt/a/empty108/ -E ENOTDIR
 ./run --rename /mnt/a/foo108/ /mnt/a/dir108/ -E ENOTDIR
 ./run --open-file /mnt/a/foo108/ -r -R :xxx:yyy:zzz -E ENOTDIR
 TEST rename-file.py:121: Rename file over parent dir
 ./run --rename /mnt/a/foo109/ /mnt/a -E ENOTDIR
 ./run --open-file /mnt/a/foo109/ -r -R :xxx:yyy:zzz -E ENOTDIR
 ***
 *** ./run --ov --ts=0 rename-empty-dir
 ***
 TEST rename-empty-dir.py:10: Rename empty dir and rename back
 ./run --rename /mnt/a/empty100 /mnt/a/no_dir100 -E EXDEV
 /mnt/a/empty100: Expected error (Invalid cross-device link) was not produced

Compare to the 4.11.0-1006.6 azure kernel test result [1], it did run through the test:

BIt's worthy to note that this test was not triggered between 4.11.0-1006.6 and 4.11.0-1014.14
