From ec37a58fba289d53f35442ad0ef3b469412efd20 Mon Sep 17 00:00:00 2001 From: Trond Myklebust Date: Wed, 29 Aug 2018 09:30:19 -0400 Subject: SUNRPC: Don't wake queued RPC calls multiple times in xprt_transmit Rather than waking up the entire queue of RPC messages a second time, just wake up the task that was put to sleep.
