From 03f02c7657f7948ab980280c54c9366f962b1474 Mon Sep 17 00:00:00 2001 From: Nadia Derbey Date: Thu, 18 Oct 2007 23:40:51 -0700 Subject: 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.
