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/sem.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'ipc/sem.c') diff --git a/ipc/sem.c b/ipc/sem.c index e4df102f3404..26f8e37fcdcb 100644 --- a/ipc/sem.c +++ b/ipc/sem.c @@ -1294,7 +1294,7 @@ static int semctl_info(struct ipc_namespace *ns, int semid, int cmd, void __user *p) { struct seminfo seminfo; - int max_id; + int max_idx; int err; err = security_sem_semctl(NULL, cmd); @@ -1318,11 +1318,11 @@ static int semctl_info(struct ipc_namespace *ns, int semid, seminfo.semusz = SEMUSZ; seminfo.semaem = SEMAEM; } - max_id = ipc_get_maxid(&sem_ids(ns)); + max_idx = ipc_get_maxidx(&sem_ids(ns)); up_read(&sem_ids(ns).rwsem); if (copy_to_user(p, &seminfo, sizeof(struct seminfo))) return -EFAULT; - return (max_id < 0) ? 0 : max_id; + return (max_idx < 0) ? 0 : max_idx; } static int semctl_setval(struct ipc_namespace *ns, int semid, int semnum, -- cgit v1.2.3-55-g7522
