By reordering elements in bond_slave structure, holes can be removed and saves a cache line. Before: structure size: 136, sum holes: 10, cachelines:3 After : structure size: 128, sum holes: 2, cachelines:2 Signed-off-by: Bhanuprakash Bodireddy <[email protected]> Signed-off-by: Ben Pfaff <[email protected]>
