From 27c331a174614208d0b539019583990967ad9479 Mon Sep 17 00:00:00 2001 From: Manfred Spraul Date: Tue, 21 Aug 2018 22:02:00 -0700 Subject: ipc/util.c: further variable name cleanups The varable names got a mess, thus standardize them again: id: user space id. Called semid, shmid, msgid if the type is known. Most functions use "id" already. idx: "index" for the idr lookup Right now, some functions use lid, ipc_addid() already uses idx as the variable name. seq: sequence number, to avoid quick collisions of the user space id key: user space key, used for the rhash tree Link: http://lkml.kernel.org/r/20180712185241.4017-12-manfred@colorfullife.com Signed-off-by: Manfred Spraul Cc: Dmitry Vyukov Cc: Davidlohr Bueso Cc: Davidlohr Bueso Cc: Herbert Xu Cc: Kees Cook Cc: Michael Kerrisk Cc: Michal Hocko Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- ipc/msg.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'ipc/msg.c') diff --git a/ipc/msg.c b/ipc/msg.c index ee78dad90460..883642cf2b27 100644 --- a/ipc/msg.c +++ b/ipc/msg.c @@ -456,7 +456,7 @@ static int msgctl_info(struct ipc_namespace *ns, int msqid, int cmd, struct msginfo *msginfo) { int err; - int max_id; + int max_idx; /* * We must not return kernel stack data. @@ -483,9 +483,9 @@ static int msgctl_info(struct ipc_namespace *ns, int msqid, msginfo->msgpool = MSGPOOL; msginfo->msgtql = MSGTQL; } - max_id = ipc_get_maxid(&msg_ids(ns)); + max_idx = ipc_get_maxidx(&msg_ids(ns)); up_read(&msg_ids(ns).rwsem); - return (max_id < 0) ? 0 : max_id; + return (max_idx < 0) ? 0 : max_idx; } static int msgctl_stat(struct ipc_namespace *ns, int msqid, -- cgit v1.2.3-59-g8ed1b
