[Qemu-devel] [PATCH v2 0/5] block: keep AioContext pointer in BlockBacke


From: Fam Zheng
Subject: [Qemu-devel] [PATCH v2 0/5] block: keep AioContext pointer in BlockBackend
Date: Tue, 27 Sep 2016 14:37:51 +0800

The first patches clean up usage of BlockBackend and changing of its (root's)
aio contexts; the last patch is an update of Stefan's previous version rebasing
on top of current master. The biggest change from the RFC is that blk_insert_bs
callers are responsible to put the BB and BDS on the same context before
calling it.

This fixes the crash triggered by "change" a scsi-cd on a virtio-scsi dataplane
device.

The new assertions in block-backend.c ensures we won't have a conflict pair of
BlockBackend users from different contextes.

Fam Zheng (4):
  blockdev-mirror: Sanity check before moving target_bs AioContext
  blockdev: Move BDS AioContext before inserting to BB
  block: Introduce and make use of blk_new_with_root
  migration: Set correct AioContext to BlockBackend

Stefan Hajnoczi (1):
  block: keep AioContext pointer in BlockBackend
