From: Julia Lawall <julia@xxxxxxx> Use kcalloc rather than the combination of kmalloc and memset. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression x,y,flags; statement S; type T; @@ x = - kmalloc + kcalloc ( - y * sizeof(T), + y, sizeof(T), flags); if (x == NULL) S -memset(x, 0, y * sizeof(T)); // </smpl> Signed-off-by: Julia Lawall <julia@xxxxxxx> --- arch/x86/kernel/uv_time.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) diff -u -p a/arch/x86/kernel/uv_time.c b/arch/x86/kernel/uv_time.c --- a/arch/x86/kernel/uv_time.c +++ b/arch/x86/kernel/uv_time.c @@ -149,10 +149,9 @@ static __init int uv_rtc_allocate_timers { int cpu; - blade_info = kmalloc(uv_possible_blades * sizeof(void *), GFP_KERNEL); + blade_info = kcalloc(uv_possible_blades, sizeof(void *), GFP_KERNEL); if (!blade_info) return -ENOMEM; - memset(blade_info, 0, uv_possible_blades * sizeof(void *)); for_each_present_cpu(cpu) { int nid = cpu_to_node(cpu); -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
