Eryu, Vivek found a bug with the index nlink accounting of the index feature that was introduced in kernel v4.13. The bug was there from the first implementation of index and the tests I wrote to verify nlink accounting (overlay/033,034) did not cover the bug use case. The first regression test (overlay/047) demonstrates the effects of the bug on end user. The second regression test (overlay/048) adds the missing test coverage of the existing nlink accounting tests. The kernel bug was hiding a bug in test overlay/042, so Vivek's kernel fix broke the test. The last patch fixes the wrong/broken test. Amir.
