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

Merged into cifs-2.6.git for-next

Made a trivial tab/space correction in the patch (pointed out by
checkpatch) and then added a trivial followon patch to address a
comment/style (trivial)
issue pointed out by checkpatch and to add a little more detailed
comments about generally when to use each debug function.  If any
objections let me know.
