[linux-cifs-client] [RFC] [PATCH] On cifs mount failure getting root inode - need to disconnect share and server session

[Steve French]

When cifs mount succeeds in connecting to the server, but fails to get
the root inode, although it returns an error to mount, it does not
free the tree connection.   This patch fixes that (I noticed this in
testing IPC$ support, ie network named pipe support - since
QueryPathInfo on a pipe over cifs returns an error).
