Besides, they give no optimization being inline as they perform calls inside in any case. Moving them into ipc/util.c saves 500 bytes of vmlinux and shortens IPC internal API. $ ./scripts/bloat-o-meter vmlinux-orig vmlinux add/remove: 3/2 grow/shrink: 0/10 up/down: 490/-989 (-499) function old new delta ipcget - 392 +392 ipc_lock_check_down - 49 +49 ipc_lock_check - 49 +49 sys_semget 119 105 -14 sys_shmget 108 86 -22 sys_msgget 100 78 -22 do_msgsnd 665 631 -34 do_msgrcv 680 644 -36 do_shmat 771 733 -38 sys_msgctl 1302 1229 -73 ipcget_new 80 - -80 sys_semtimedop 1534 1452 -82 sys_semctl 2034 1922 -112 sys_shmctl 1919 1765 -154 ipcget_public 322 - -322 The ipcget() growth is the result of gcc inlining of currently static ipcget_new/_public.
