      "message": "namespaces: move the IPC namespace under IPC_NS option\n\nCurrently the IPC namespace management code is spread over the ipc/*.c files.\nI moved this code into ipc/namespace.c file which is compiled out when needed.\n\nThe linux/ipc_namespace.h file is used to store the prototypes of the\nfunctions in namespace.c and the stubs for NAMESPACES\u003dn case.  This is done\nso, because the stub for copy_ipc_namespace requires the knowledge of the\nCLONE_NEWIPC flag, which is in sched.h.  But the linux/ipc.h file itself in\nincluded into many many .c files via the sys.h-\u003esem.h sequence so adding the\nsched.h into it will make all these .c depend on sched.h which is not that\ngood.  On the other hand the knowledge about the namespaces stuff is required\nin 4 .c files only.\n\nBesides, this patch compiles out some auxiliary functions from ipc/sem.c,\nmsg.c and shm.c files.  It turned out that moving these functions into\nnamespaces.c is not that easy because they use many other calls and macros\nfrom the original file.  Moving them would make this patch complicated.  On\nthe other hand all these functions can be consolidated, so I will send a\nseparate patch doing this a bit later.\n\nSigned-off-by: Pavel Emelyanov \u003cxemul@openvz.org\u003e\nAcked-by: Serge Hallyn \u003cserue@us.ibm.com\u003e\nCc: Cedric Le Goater \u003cclg@fr.ibm.com\u003e\nCc: \"Eric W.
