From b0810b037de0b62a3c6e3abfc123fe2734335f53 Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe Date: Wed, 6 May 2020 11:24:39 +0300 Subject: RDMA/core: Consolidate ib_create_srq flows The uverbs layer largely duplicate the code in ib_create_srq(), with the slight difference that it passes in a udata. Move all the code together into ib_create_srq_user() and provide an inline for kernel users, similar to other create calls.
