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

From: Arnaldo Carvalho de Melo
Date: Mon Jan 13 2014 - 15:54:17 EST


From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

Initial struct stats:

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

After reorg:

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