Bug Description

Kernel 4.15.0-1022.23 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

Is this only happening on the linux-azure kernel, or also with the generic kernel?

Also, do you know if this issue is a regression? If it is, we can bisect down the commit that introduced the bug.

It might be worth seeing if this is already fixed in mainline as well:

Hey Joe,

It's only spotted on the linux-azure kernel.

As we haven't test this all the way from 4.11.0-1006.6 to this cycle, I think maybe it's better to not call it a regression for this kernel.

I will test the mainline kernel once I got access to it.

This issue can be reproduced on 4.11.0-1014.13 azure kernel.

Verified with 4.14-rc6 (4.14.0-041400rc6-generic), this issue does not exist.

Verified with the oldest version in the archive: 4.11.0-1009-azure
This issue still exist.

I think we only test those kernels older than 4.11.0-1009-azure in proposed pocket.

As we have updated the upstream git repo, this bug will needs to be revisited.
