From 7ca7e564e049d8b350ec9d958ff25eaa24226352 Mon Sep 17 00:00:00 2001 From: Nadia Derbey Date: Thu, 18 Oct 2007 23:40:48 -0700 Subject: ipc: store ipcs into IDRs This patch introduces ipcs storage into IDRs. The main changes are: . This ipc_ids structure is changed: the entries array is changed into a root idr structure. . The grow_ary() routine is removed: it is not needed anymore when adding an ipc structure, since we are now using the IDR facility. . The ipc_rmid() routine interface is changed: . there is no need for this routine to return the pointer passed in as argument: it is now declared as a void . since the id is now part of the kern_ipc_perm structure, no need to have it as an argument to the routine Signed-off-by: Nadia Derbey Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- include/linux/ipc.h | 1 + 1 file changed, 1 insertion(+) (limited to 'include/linux/ipc.h') diff --git a/include/linux/ipc.h b/include/linux/ipc.h index ee111834091c..96988d1460da 100644 --- a/include/linux/ipc.h +++ b/include/linux/ipc.h @@ -89,6 +89,7 @@ struct kern_ipc_perm { spinlock_t lock; int deleted; + int id; key_t key; uid_t uid; gid_t gid; -- cgit v1.2.3
