    ipc: recompute msgmni on ipc namespace creation/removal · e2c284d8
    Nadia Derbey authored
    Introduce a notification mechanism that aims at recomputing msgmni each time
    an ipc namespace is created or removed.
    
    The ipc namespace notifier chain already defined for memory hotplug management
    is used for that purpose too.
    
    Each time a new ipc namespace is allocated or an existing ipc namespace is
    removed, the ipcns notifier chain is notified.  The callback routine for each
    registered ipc namespace is then activated in order to recompute msgmni for
    that namespace.
