Subject: [PATCH v2 1/2] cifs: alloc_path_with_tree_prefix: do not append sep. if the path is empty
Date: Fri, 14 Jan 2022 22:53:00 +0300 [thread overview]
Message-ID: <YeHUnI1nTkThNMqv@himera.home> (raw)
alloc_path_with_tree_prefix() concatenates tree prefix and the path.
Windows CIFS client does not add separator after the tree prefix if the path
is empty. Let's do the same.
This fixes mounting DFS namespaces with names containing non-ASCII symbols.
