To make sure I don't miss any (it seems I missed recvmmsg and sendmmsg for
the socketcall case, sigh), this is the list of ipc syscalls to implement?
sys_msgget
sys_msgctl
sys_msgrcv
sys_msgsnd
sys_semget
sys_semctl
sys_semtimedop
sys_shmget
sys_shmctl
sys_shmat
sys_shmdt
sys_semop() seems to be unneeded because it can be implemented using
sys_semtimedop()?
Thanks!
