v2: - Drop patch 4 in v1. A second thought made me feel neither it nor Kevin's
suggestion to move the BH process to bdrv_drain_recurse/BDRV_POLL_WHILE
is a complete fix. So leave it for a separate patch.
- Add rev-by to patches 1, 3, 4.
- Split from patch 1 in v1 and add patch 2, for the new assertions. [Kevin]
- Rewrite patch 5. Fix block job's co when a BDS is moved to a different
aio context. [Kevin]
- Add patch 6.
Crashes are reported on dataplane devices when doing snapshot and commit under
guest I/O.
With this series, Ed's test case '176' now passes (reran 10+ times):
https://github.com/skyportsystems/qemu-1/commits/eswierk-iotests-2.9
The biggest fix for this is patch 5, which fixes a race condition between main
thread and iothread.
Fam Zheng (6):
block: Fix unpaired aio_disable_external in external snapshot
block: Assert attached child node has right aio context
mirror: Fix aio context of mirror_top_bs
block: Quiesce old aio context during bdrv_set_aio_context
coroutine: Explicitly specify AioContext when entering coroutine
tests/block-job-txn: Don't start block job before adding to txn
