Dear XFS Members,

In the XFS test suite there is a test case generic/314 "Test SGID inheritance on subdirectories". It is not specific to a particular filesystem thus selected for both xfs or ext4 test runs. In other words, the same behaviour is expected and enforced for XFS and EXT4.

However, I have been told that EXT4 and XFS may have different behaviour as the setgid-directory behavior is not guaranteed to work the same way on all filesystems.

Shall XFS test case reflect that difference or enforcing the same behaviour is appropriate?

Best regards,
