CIFS: Adds information-level logging function (9a0efecc) · Commits · 戴 / test

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. Signed-off-by:
