Subject: [PATCH 2.6.17-rc5-mm2 10/18] sbp2: log number of supported concurrent logins
Date: Fri, 2 Jun 2006 22:11:17 +0200 (CEST)	[thread overview]
Message-ID: <tkrat.5222feb4e2593ac0@s5r6.in-berlin.de> (raw)
In-Reply-To: <tkrat.9a30b61b3f17e5ac@s5r6.in-berlin.de>

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.
