From ed262287e2b46927905a41e86100a63dc2327dac Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Mon, 8 Jan 2018 11:00:43 -0800 Subject: [PATCH] IB/srpt: Rename a local variable, a member variable and a constant Rename rsp_size into max_rsp_size and SRPT_RQ_SIZE into MAX_SRPT_RQ_SIZE. The new names better reflect the role of this member variable and constant. Since the prefix "srp_" is superfluous in the context of the function that creates an RDMA channel, rename srp_sq_size into sq_size.
