Subject: [PATCH 15/38] perf trace: Pack 'struct trace'

From: Arnaldo Carvalho de Melo <acme@...hat.com>

Initial struct stats:

	/* size: 368, cachelines: 6, members: 24 */
	/* sum members: 353, holes: 3, sum holes: 15 */
	/* last cacheline: 48 bytes */

After reorg:

[acme@...andy linux]$ pahole -C trace ~/bin/trace | tail -4
	/* size: 360, cachelines: 6, members: 24 */
	/* padding: 7 */
	/* last cacheline: 40 bytes */
};
[acme@...andy linux]$
