Subject: [PATCH v3 1/2] CIFS: Adds information-level logging function
Date:   Sun,  7 Oct 2018 12:21:25 -0300
Message-Id: <3e9246011e68c3ebeea111c8bb743d1a189ce6ac.1538873915.git.rfreire@redhat.com>
In-Reply-To: <cover.1538873915.git.rfreire@redhat.com>
References: <cover.1538873915.git.rfreire@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Currently, CIFS lacks a internal logging function that prints out data
when CIFS_DEBUG=n. When CIFS_DEBUG=y, the only message level for CIFS
events are KERN_ERR or KERN_DEBUG.

This patch creates cifs_info(), which is useful for printing
non-critical event messges, at either CIFS_DEBUG state.
