From c0fa3ad9d652abd8bceba72a61a1637bf3d930f0 Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Wed, 5 Oct 2011 11:42:29 +1100 Subject: [PATCH] audit: always follow va_copy() with va_end() A call to va_copy() should always be followed by a call to va_end() in the same function. In kernel/autit.c::audit_log_vformat() this is not always done. This patch makes sure va_end() is always called.
