From a937693a82fd2211c5e52b638959d1486a77d16a Mon Sep 17 00:00:00 2001 From: Chuck Lever Date: Mon, 18 Dec 2023 17:31:54 -0500 Subject: svcrdma: Add back svcxprt_rdma::sc_read_complete_q Having an nfsd thread waiting for an RDMA Read completion is problematic if the Read responder (ie, the client) stops responding. We need to go back to handling RDMA Reads by allowing the nfsd thread to return to the svc scheduler, then waking a second thread finish the RPC message once the Read completion fires. As a next step, add a list_head upon which completed Reads are queued. A subsequent patch will make use of this queue.
