[Qemu-devel] [PATCH for-2.11 0/4] Fix qemu-iotests failures

From: Kevin Wolf
Subject: [Qemu-devel] [PATCH for-2.11 0/4] Fix qemu-iotests failures
Date: Tue, 28 Nov 2017 16:43:46 +0100

This reverts the recent fix for the case of qemu-iotests 200 (block job
completion races when using a separate I/O thread) that only fixed a
symptom and caused many regressions, and replaces it with a new
solution that hopefully attacks the right root cause.

The series also contains a bonus fix for a bug that was uncovered by the
different timing with the patches that are reverted here.

Kevin Wolf (4):
  Revert "coroutine: abort if we try to schedule or enter a pending
  Revert "blockjob: do not allow coroutine double entry or
  coroutine: Cancel aio_co_schedule() on direct entry
  block: Expect graph changes in bdrv_parent_drained_begin/end
