be2net: move txcp field in be_tx_obj to eliminate holes in the struct
Before patch: struct be_tx_obj { u32 db_offset; /* 0 4 */ /* XXX 4 bytes hole, try to pack */ struct be_queue_info q; /* 8 56 */ /* --- cacheline 1 boundary (64 bytes) --- */ struct be_queue_info cq; /* 64 56 */ struct be_tx_compl_info txcp; /* 120 4 */ /* XXX 4 bytes hole, try to pack */ /* --- cacheline 2 boundary (128 bytes) --- */ struct sk_buff * sent_skb_list[2048]; /* 128 16384 */ ... }: After patch: struct be_tx_obj { u32 db_offset; /* 0 4 */ struct be_tx_compl_info txcp; /* 4 4 */ struct be_queue_info q; /* 8 56 */ /* --- cacheline 1 boundary (64 bytes) --- */ struct be_queue_info cq; /* 64 56 */ struct sk_buff * sent_skb_list[2048]; /* 120 16384 */ ... }; Signed-off-by: Ivan Vecera <cera@cera.cz> Signed-off-by: David S.
