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 <rolandd@cisco.com> Acked-by: Faisal Latif <flatif@neteffect.com>
