msgmap usage

[Fedon Kadifeli]

Is there a method to determine the current usage of the msgmap array? I presume that the free-space resource map for message queues is a very dynamic structure, but knowing the "average" number of full elements in this array (in other words, the "average" number of free-space fragments in the shared memory message space) may be useful for tuning the msg-related kernel parameters before getting a "mfree map overflow" error.

Glance shows the usage of msgmni. That's all I know of
