The following patchset fixes the bug. The test case (verified by me): 1. At Windows, create DFS namespace with name containing non-ASCII symbols (for example дфс) 2. At Linux SMB client (kernel must be built with CONFIG_CIFS_DFS_UPCALL) execute command /sbin/mount.cifs //<smb_server>/дфс /tmp/dfs -o domain=...,user=...,password=... 3. ls /tmp/dfs/<existing_dfs_ref> -> (before the patchset applied) error "No such file or directory" -> (after the patchset applied) result of successful ls 4. ls /tmp/dfs/<non_existing_dfs_ref> -> (before the patchset applied) error "No such file or directory" -> (after the patchset applied) error "No such file or directory" -- Eugene
