Sadly, as I suspected in my last review of http://review.whamcloud.com/5164 this is causing test failures in the VM environment. Jinshan, can you please submit a patch to check for VM and use error_ignore in case the performance is worse. We still want to run the test, to make sure that the functionality is working. |
