  "message": "IPC: make struct ipc_ids static in ipc_namespace\n\nEach ipc_namespace contains a table of 3 pointers to struct ipc_ids (3 for\nmsg, sem and shm, structure used to store all ipcs) These \u0027struct ipc_ids\u0027\nare dynamically allocated for each icp_namespace as the ipc_namespace\nitself (for the init namespace, they are initialized with pointers to\nstatic variables instead)\n\nIt is so for historical reason: in fact, before the use of idr to store the\nipcs, the ipcs were stored in tables of variable length, depending of the\nmaximum number of ipc allowed.  Now, these \u0027struct ipc_ids\u0027 have a fixed\nsize.  As they are allocated in any cases for each new ipc_namespace, there\nis no gain of memory in having them allocated separately of the struct\nipc_namespace.\n\nThis patch proposes to make this table static in the struct ipc_namespace.\nThus, we can allocate all in once and get rid of all the code needed to\nallocate and free these ipc_ids separately.\n\nSigned-off-by: Pierre Peiffer \u003cpierre.peiffer@bull.net\u003e\nAcked-by: Cedric Le Goater \u003cclg@fr.ibm.com\u003e\nCc: Pavel Emelyanov \u003cxemul@openvz.org\u003e\nCc: Nadia Derbey \u003cNadia.Derbey@bull.net\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
