[PATCH] SELinux: convert to kzalloc
This patch converts SELinux code from kmalloc/memset to the new kazalloc unction. On i386, this results in a text saving of over 1K. Before: text data bss dec hex filename 86319 4642 15236 106197 19ed5 security/selinux/built-in.o After: text data bss dec hex filename 85278 4642 15236 105156 19ac4 security/selinux/built-in.o Signed-off-by: James Morris <jmorris@namei.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
