Storing ipcs into IDRs
This patch converts casts of struct kern_ipc_perm to
. struct msg_queue
. struct sem_array
. struct shmid_kernel
into the equivalent container_of() macro. It improves code maintenance
because the code need not change if kern_ipc_perm is no longer at the
beginning of the containing struct.
