Hi, When posting: [PATCH 1/8] Scaling msgmni to the amount of lowmem (see http://lkml.org/lkml/2008/2/11/171), I have added a KERN_INFO message that is output each time msgmni is recomputed. In http://lkml.org/lkml/2008/4/29/575 Tony Luck complained that this message references an ipc namespace address that is useless. I first thought of using an audit_log instead of a printk, as suggested by Serge Hallyn. But unfortunately, we do not have any other information than the namespace address to provide here too. So I chose to move the message and output it only at boot time, removing the reference to the namespace. This patch applies to 2.6.26-rc2-mm1.
