From 40a5f1b19bacb2de7a051be952dee85e38c9e5f5 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Fri, 27 May 2016 10:39:50 -0400 Subject: SUNRPC: RPC transport queue must be low latency rpciod can easily get congested due to the long list of queued rpc_tasks. Having the receive queue wait in turn for those tasks to complete can therefore be a bottleneck. Address the problem by separating the workqueues into: - rpciod: manages rpc_tasks - xprtiod: manages transport related work.
