From fc55d2c9448b34218ca58733a6f51fbede09575b Mon Sep 17 00:00:00 2001 From: "Yan, Zheng" Date: Thu, 31 Oct 2013 09:10:47 +0800 Subject: [PATCH] ceph: wake up 'safe' waiters when unregistering request We also need to wake up 'safe' waiters if error occurs or request aborted. Otherwise sync(2)/fsync(2) may hang forever.
