      The patch for LU-12026, https://review.whamcloud.com/36286/, added test 104 to sanityn. It landed to master on October 2019 and landed to b2_12 on 17 JAN 2020.

      sanityn test 104 does not have a Lustre version check, but needs one. Master, future 2.14.0, interop testing runs with 2.12.3 and 2.13.0. 2.13.0 already has this patch and 2.12.4 has this patch. So, when we move interop testing for master to use 2.12.4, we don’t have to worry about master interop testing hitting this issue. The only other release we need to worry about is the LTS branch b2_12. The 2.12 branch runs interop testing with 2.11.0 and 2.10.8. Thus, if we land a patch to b2_12 that checks the server version to make sure it is 2.12.3.110 or later, then all b2_12 interop testing should skip this test when appropriate.
