Subject: [SMB3] Update session and share information displayed for debugging SMB2/SMB3
X-Git-Tag: v4.14-rc2~16^2~6
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1fa089ec6d68849bfe60abd141375dc9b21b0ee8;p=platform%2Fkernel%2Flinux-exynos.git

[SMB3] Update session and share information displayed for debugging SMB2/SMB3

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.
