With current mainline (5.11 + all fixes in 5.12-rc1 + the 6 pending patches from Paulo and Aurelien), all DFS tests pass. DFS quality looks good. I am going to hold off the fix for slash ('\') in paths until later to make sure it doesn't break DFS. Let Paulo and us know if anyone has more tests that need to be added for DFS scenarios. http://smb3-test-rhel-75.southcentralus.cloudapp.azure.com/#/builders/3/builds/93 I am also trying to add more tests to the cifs-testing group - there has been some recent progress (e.g. adding more tests for swapfiles on cifs mounts) but going test by test finding the missing features can be time consuming so more data on specific things that would help us add more tests would be helpful. -- Thanks, Steve
