[PATCH v3 0/2] CIFS: Info-level log support, print message when attempting mount.

Hi Steve,
>From our conversation over v2, I came out with this v3 patch, which I broke
in two commits:

* The first commit in cifs_debug.h, creating the cifs_info() function.
- The aim of this commit is to allow to the developer to be able to print
informational-level data without having to use pr_info, pr_notice etc,
in line with other filesystems.
. One interesting and noteworthy feature of cifs_info() is that it is
transparent to the CIFS_DEBUG config state, either in "y" or "n".
. Also, by using KERN_INFO level, it can be safely filtered by a
maintainer / administrator, without cluttering their log monitors,
since this is a low level alert.
- I took the liberty to not add it inside the existing pr_debug, because
of the eventual need of some developer to print stuff that should be
printed not only in CIFS_DEBUG mode (as there are plenty of pr_notice
scattered over the code).
- Also, this is not a debug but a info message, so i liked cifs_info()
more ;-)
- I saw plenty of pr_notice() in CIFS code, but I resisted the urge to
convert them to cifs_info().

* The second commit contains the code printing a cifs_info() when attempting
a CIFS mount operation.

Appreciate your review.

V3: Created a new cifs_info() function, moved the mount attempt message to
cifs_info

V2: Created a loop to select the right cifs_dbg message to be printed,
considering the current system's scenario, in order to avoid a
duplicate message or stripping out important information in
debug.
