Subject: [RFC 08/19] staging: qlge: reorder members of qlge_adapter for optimization
Date: Mon, 21 Jun 2021 21:48:51 +0800 [thread overview]
Message-ID: <20210621134902.83587-9-coiby.xu@gmail.com> (raw)
In-Reply-To: <20210621134902.83587-1-coiby.xu@gmail.com>
Before reordering, pahole shows,
/* size: 21168, cachelines: 331, members: 69 */
/* sum members: 21144, holes: 4, sum holes: 18 */
/* padding: 6 */
/* paddings: 6, sum paddings: 24 */
/* forced alignments: 1 */
/* last cacheline: 48 bytes */
After reordering following pahole's suggestion,
/* size: 21152, cachelines: 331, members: 69 */
/* sum members: 21144, holes: 1, sum holes: 2 */
/* padding: 6 */
/* paddings: 6, sum paddings: 24 */
/* forced alignments: 1 */
/* last cacheline: 32 bytes */
