[PATCH] audit inode patch
Previously, we were gathering the context instead of the sid. Now in this patch, we gather just the sid and convert to context only if an audit event is being output. This patch brings the performance hit from 146% down to 23% Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
