Reorder members of struct ocelot_port to eliminate holes and reduce structure size. Pahole says: Before: struct ocelot_port { struct ocelot * ocelot; /* 0 8 */ struct regmap * target; /* 8 8 */ bool vlan_aware; /* 16 1 */ /* XXX 7 bytes hole, try to pack */ const struct ocelot_bridge_vlan * pvid_vlan; /* 24 8 */ unsigned int ptp_skbs_in_flight; /* 32 4 */ u8 ptp_cmd; /* 36 1 */ /* XXX 3 bytes hole, try to pack */ struct sk_buff_head tx_skbs; /* 40 96 */ /* --- cacheline 2 boundary (128 bytes) was 8 bytes ago --- */ u8 ts_id; /* 136 1 */ /* XXX 3 bytes hole, try to pack */ phy_interface_t phy_mode; /* 140 4 */ bool is_dsa_8021q_cpu; /* 144 1 */ bool learn_ena; /* 145 1 */ /* XXX 6 bytes hole, try to pack */ struct net_device * bond; /* 152 8 */ bool lag_tx_active; /* 160 1 */ /* XXX 1 byte hole, try to pack */ u16 mrp_ring_id; /* 162 2 */ /* XXX 4 bytes hole, try to pack */ struct net_device * bridge; /* 168 8 */ int bridge_num; /* 176 4 */ u8 stp_state; /* 180 1 */ /* XXX 3 bytes hole, try to pack */ int speed; /* 184 4 */ /* size: 192, cachelines: 3, members: 18 */ /* sum members: 161, holes: 7, sum holes: 27 */ /* padding: 4 */ }; After: struct ocelot_port { struct ocelot * ocelot; /* 0 8 */ struct regmap * target; /* 8 8 */ struct net_device * bond; /* 16 8 */ struct net_device * bridge; /* 24 8 */ const struct ocelot_bridge_vlan * pvid_vlan; /* 32 8 */ phy_interface_t phy_mode; /* 40 4 */ unsigned int ptp_skbs_in_flight; /* 44 4 */ struct sk_buff_head tx_skbs; /* 48 96 */ /* --- cacheline 2 boundary (128 bytes) was 16 bytes ago --- */ u16 mrp_ring_id; /* 144 2 */ u8 ptp_cmd; /* 146 1 */ u8 ts_id; /* 147 1 */ u8 stp_state; /* 148 1 */ bool vlan_aware; /* 149 1 */ bool is_dsa_8021q_cpu; /* 150 1 */ bool learn_ena; /* 151 1 */ bool lag_tx_active; /* 152 1 */ /* XXX 3 bytes hole, try to pack */ int bridge_num; /* 156 4 */ int speed; /* 160 4 */ /* size: 168, cachelines: 3, members: 18 */ /* sum members: 161, holes: 1, sum holes: 3 */ /* padding: 4 */ /* last cacheline: 40 bytes */ }; Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org> |
