Subject: [PATCH] [SMB3] Update session and share information displayed for
debugging SMB2/SMB3
Git-commit: 1fa089ec6d68849bfe60abd141375dc9b21b0ee8
Patch-mainline: v4.14-rc2
References: bsc#1144333
We were not displaying some key fields (session status and capabilities and
whether guest authenticated) for SMB2/SMB3 session in /proc/fs/cifs/DebugData.
This is needed for real world triage of problems with the (now much more
common) SMB3 mounts.
