The patch titled
ieee1394: sbp2: log number of supported concurrent logins
has been added to the -mm tree. Its filename is

See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this
------------------------------------------------------
Subject: ieee1394: sbp2: log number of supported concurrent logins
From: Stefan Richter <stefanr@xxxxxxxxxxxxxxxxx>
Since this is useful information, promote it from a debug macro to
a regular log message. The message appears only if the user set
exclusive_login=0, therefore won't clutter the logs in normal use.
Also update the comment on exclusive_login.
