commit
f446a630802f154ef0087771683bd4f8e9d08384 upstream.
Return the DFS root session id in /proc/fs/cifs/DebugData to make it
easier to track which IPC tcon was used to get new DFS referrals for a
specific connection, and aids in debugging.
A simple output of it would be
Sessions:
1) Address: 192.168.1.13 Uses: 1 Capability: 0x300067 Session Status: 1
Security type: RawNTLMSSP SessionId: 0xd80000000009
User: 0 Cred User: 0
DFS root session id: 0x128006c000035
