From 47b0edcb599ea6eb9ef16d3a08932a0e01485293 Mon Sep 17 00:00:00 2001 From: Thomas Meyer Date: Tue, 29 Nov 2011 22:08:00 +0100 Subject: tracing/trivial: Use kcalloc instead of kzalloc to allocate array The advantage of kcalloc is, that will prevent integer overflows which could result from the multiplication of number of elements and size and it is also a bit nicer to read. The semantic patch that makes this change is available in https://lkml.org/lkml/2011/11/25/107 Link: http://lkml.kernel.org/r/1322600880.1534.347.camel@localhost.localdomain Signed-off-by: Thomas Meyer Signed-off-by: Steven Rostedt --- kernel/trace/trace_syscalls.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'kernel/trace/trace_syscalls.c') diff --git a/kernel/trace/trace_syscalls.c b/kernel/trace/trace_syscalls.c index cb654542c1a1..43500153dd1e 100644 --- a/kernel/trace/trace_syscalls.c +++ b/kernel/trace/trace_syscalls.c @@ -468,8 +468,8 @@ int __init init_ftrace_syscalls(void) unsigned long addr; int i; - syscalls_metadata = kzalloc(sizeof(*syscalls_metadata) * - NR_syscalls, GFP_KERNEL); + syscalls_metadata = kcalloc(NR_syscalls, sizeof(*syscalls_metadata), + GFP_KERNEL); if (!syscalls_metadata) { WARN_ON(1); return -ENOMEM; -- cgit v1.2.3
