From 8b9a30ca5bc10545637429486836f3c206c39fab Mon Sep 17 00:00:00 2001 From: Fam Zheng Date: Tue, 24 Jun 2014 20:26:37 +0800 Subject: [PATCH] qemu-iotests: Test BLOCK_JOB_READY event for 0Kb image active commit There should be a BLOCK_JOB_READY event with active commit, regardless of image length. Let's test the 0 length image case, and make sure it goes through the ready->complete process.
