From 35525b79786b2ba58ef13822198ce22c497bc7a2 Mon Sep 17 00:00:00 2001 From: Andriy Skulysh Date: Mon, 7 Jan 2013 00:12:15 +0200 Subject: sunrpc: Fix lockd sleeping until timeout There is a race in enqueueing thread to a pool and waking up a thread. lockd doesn't wake up on reception of lock granted callback if svc_wake_up() is called before lockd's thread is added to a pool.
