From 5c93f56f770e69c4cf2dbaebecd6bcca205949f9 Mon Sep 17 00:00:00 2001 From: Amitoj Kaur Chawla Date: Thu, 23 Jun 2016 10:22:01 +0530 Subject: [PATCH] dlm: Use kmemdup instead of kmalloc and memcpy Replace calls to kmalloc followed by a memcpy with a direct call to kmemdup. The Coccinelle semantic patch used to make this change is as follows: @@ expression from,to,size,flag; statement S; @@ - to = \(kmalloc\|kzalloc\)(size,flag); + to = kmemdup(from,size,flag); if (to==NULL || ...) S - memcpy(to, from, size); Signed-off-by: Amitoj Kaur Chawla Signed-off-by: David Teigland --- fs/dlm/lowcomms.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff --git a/fs/dlm/lowcomms.c b/fs/dlm/lowcomms.c index 1ab012a27d9f..963016c8f3d1 100644 --- a/fs/dlm/lowcomms.c +++ b/fs/dlm/lowcomms.c @@ -1279,10 +1279,9 @@ static void init_local(void) if (dlm_our_addr(&sas, i)) break; - addr = kmalloc(sizeof(*addr), GFP_NOFS); + addr = kmemdup(&sas, sizeof(*addr), GFP_NOFS); if (!addr) break; - memcpy(addr, &sas, sizeof(*addr)); dlm_local_addr[dlm_local_count++] = addr; } } -- 2.20.1
