[Qemu-devel] [PATCH for-2.9 0/5] block: Fixes regarding dataplane and ma


From: Fam Zheng
Subject: [Qemu-devel] [PATCH for-2.9 0/5] block: Fixes regarding dataplane and management operations
Date: Thu, 6 Apr 2017 22:25:22 +0800

These are accumulated fixes that showed up when working on the "change"
issue and "repeated snapshot + commit" crash on dataplane:

    [Qemu-devel] [PATCH] blk: fix aio context loss on media change
        - Vladimir Sementsov-Ogievskiy <address@hidden>

    [Qemu-devel] New iotest repros failures on virtio external snapshot with
    iothread
        - Ed Swierk <address@hidden>

Specifically, patch 4 is an output of the former, and the rest are from the
latter. They seem quite related hence this one series.

With this series applied, Ed's test case '176' passes (reran 10+ times):

NOTE: The "change" crash still needs Vladimir's fix. Patch 4 is noticed with a
few not-so-related WIP patches, but my understanding is this is a latent bug
and IMO the change is rather harmless to have.

Fam Zheng (5):
  block: Fix unpaired aio_disable_external in external snapshot
  mirror: Fix aio context of mirror_top_bs
  block: Quiesce old aio context during bdrv_set_aio_context
  block: Drain BH in bdrv_drained_begin
  coroutine: Explicitly specify AioContext when creating coroutine
