From 1ff66e8c1faee7c2711b84b9c89e1c5fcd767839 Mon Sep 17 00:00:00 2001 From: Roland Dreier Date: Mon, 14 Jul 2008 23:48:49 -0700 Subject: RDMA/nes: Encapsulate logic nes_put_cqp_request() The iw_nes driver repeats the logic if (atomic_dec_and_test(&cqp_request->refcount)) { if (cqp_request->dynamic) { kfree(cqp_request); } else { spin_lock_irqsave(&nesdev->cqp.lock, flags); list_add_tail(&cqp_request->list, &nesdev->cqp_avail_reqs); spin_unlock_irqrestore(&nesdev->cqp.lock, flags); } } over and over. Wrap this up in functions nes_free_cqp_request() and nes_put_cqp_request() to simplify such code. In addition to making the source smaller and more readable, this shrinks the compiled code quite a bit: add/remove: 2/0 grow/shrink: 0/13 up/down: 164/-1692 (-1528) function old new delta nes_free_cqp_request - 147 +147 nes_put_cqp_request - 17 +17 nes_modify_qp 2316 2293 -23 nes_hw_modify_qp 737 657 -80 nes_dereg_mr 945 860 -85 flush_wqes 501 416 -85 nes_manage_apbvt 648 560 -88 nes_reg_mr 1117 1026 -91 nes_cqp_ce_handler 927 769 -158 nes_alloc_mw 1052 884 -168 nes_create_qp 5314 5141 -173 nes_alloc_fmr 2212 2035 -177 nes_destroy_cq 1097 918 -179 nes_create_cq 2787 2598 -189 nes_dealloc_mw 762 566 -196 Signed-off-by: Roland Dreier Acked-by: Faisal Latif --- drivers/infiniband/hw/nes/nes.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'drivers/infiniband/hw/nes/nes.h') diff --git a/drivers/infiniband/hw/nes/nes.h b/drivers/infiniband/hw/nes/nes.h index 61b46e9c7d2d..fe88bec48949 100644 --- a/drivers/infiniband/hw/nes/nes.h +++ b/drivers/infiniband/hw/nes/nes.h @@ -538,6 +538,10 @@ void nes_read_1G_phy_reg(struct nes_device *, u8, u8, u16 *); void nes_write_10G_phy_reg(struct nes_device *, u16, u8, u16, u16); void nes_read_10G_phy_reg(struct nes_device *, u8, u8, u16); struct nes_cqp_request *nes_get_cqp_request(struct nes_device *); +void nes_free_cqp_request(struct nes_device *nesdev, + struct nes_cqp_request *cqp_request); +void nes_put_cqp_request(struct nes_device *nesdev, + struct nes_cqp_request *cqp_request); void nes_post_cqp_request(struct nes_device *, struct nes_cqp_request *, int); int nes_arp_table(struct nes_device *, u32, u8 *, u32); void nes_mh_fix(unsigned long); -- cgit
