[PATCH 2/2] CIFS: adds min_offload and other params to cifs_debug

[aman1cifs@gmail.com]

From: Aman <aman1@microsoft.com>

This change adds more parameters for debugging into the status of all
channels. It adds the following TCP server parameters to cifs_debug.c

        - min_offload
        - compression.requested
        - dfs_conn
        - ignore_signature
        - leaf_fullpath
        - retrans
        - noblockcnt
        - noblocksnd
        - sign
        - max_credits

This is a logical follow up to a previous patch titled:
"[PATCH] CIFS: Propagate min offload along with other parameters from
primary to secondary channels",
however this has been tested and applies independently.
