From 49afa55b5bd792cda4fca15d3238e9b6f370c856 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Thu, 13 May 2010 10:03:32 +0000 Subject: [PATCH] net/caif: Use kzalloc MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Use kzalloc rather than the combination of kmalloc and memset. A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // @@ expression x,size,flags; statement S; @@ -x = kmalloc(size,flags); +x = kzalloc(size,flags); if (x == NULL) S -memset(x, 0, size); // Signed-off-by: Julia Lawall Acked-by: Sjur Brændeland Signed-off-by: David S.
