This is a POTENTIAL REGRESSION.

PASSED with 4.4.0-1063-aws
FAILED with 4.4.0-1064-aws in proposed

This is a new test case added 4 days ago.
From the commit message it looks like this is a test case for commit 8db6c34f1dbc:
    The regression is introduced from 8db6c34f1dbc ("Introduce v3 namespaced
    file capabilities"). Overlayfs and possibly other networking filesystems
    unhash the dentry on unlink, fail on this test with above change.

However this commit has been applied in the Xenial AWS kernel (14985d791) with bug 1778286

This might have something to do with the way how we backport it (the EINVAL return value is the clue)
