From e3b926b4c1499ba7b1b9513aa6113944d572aba5 Mon Sep 17 00:00:00 2001 From: David Woodhouse Date: Tue, 10 May 2005 18:56:08 +0100 Subject: [PATCH] AUDIT: pass size argument to audit_expand(). Let audit_expand() know how much it's expected to grow the buffer, in the case that we have that information to hand.
