From 1ecac7fd74f2e5fb06a7719ecba55fb5778a9a47 Mon Sep 17 00:00:00 2001 From: Jun'ichi Nomura Date: Mon, 27 Mar 2006 01:17:51 -0800 Subject: [PATCH] dm flush queue EINTR If dm_suspend() is cancelled, bios already added to the deferred list need to be submitted. Otherwise they remain 'in limbo' until there's a dm_resume().
