From c376222960ae91d5ffb9197ee36771aaed1d9f90 Mon Sep 17 00:00:00 2001 From: "Robert P. J. Day" Date: Sat, 10 Feb 2007 01:45:03 -0800 Subject: [PATCH] Transform kmem_cache_alloc()+memset(0) -> kmem_cache_zalloc(). Replace appropriate pairs of "kmem_cache_alloc()" + "memset(0)" with the corresponding "kmem_cache_zalloc()" call. Signed-off-by: Robert P. J.
