From 2275cde4ccb319ae1eb1c6c717f0e547e62019ee Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Wed, 7 Feb 2018 09:13:04 -0500 Subject: SUNRPC: Queue latency-sensitive socket tasks to xprtiod The response to a write_space notification is very latency sensitive, so we should queue it to the lower latency xprtiod_workqueue. This is something we already do for the other cases where an rpc task holds the transport XPRT_LOCKED bitlock.
