Sorry for the delay but this message has been queued for 5 days (my sendmail was not correclty configured) - resending. [PATCH 01/01] This patch updates Documentation/filesystems/proc.txt: it describes the file auto_msgmni intoduced to enable/disable msgmni automatic recomputing upon memory add/remove (see thread http://lkml.org/lkml/2008/7/4/27). Also added a description for msgmni (this filex is only listed in Documentation/sysctl/kernel.txt). Applies to 2.6.27-rc1-mm1.
