git-publish [1] is a convenient tool to send patches and has been
4
popular among QEMU developers. Recently it has been made available in
5
Fedora official repo thanks to Stefan's work.

One nice feature of the tool is a per-project configuration with
8
profiles, especially in which the cccmd option is a handy method to
9
create the Cc list.

1
Commit dce8921b2baaf95974af8176406881872067adfa ("iothread: Stop threads
2
before main() quits") introduced iothread_stop_all() to avoid the
3
following virtio-scsi assertion failure:
4
1
5
assert(blk_get_aio_context(d->conf.blk) == s->ctx);
6
7
Back then the assertion failed because when bdrv_close_all() made
8
d->conf.blk NULL, blk_get_aio_context() returned the global AioContext
9
instead of s->ctx.
10
11
The same assertion can still fail today when vcpus submit new I/O
12
requests after iothread_stop_all() has moved the BDS to the global
13
AioContext.
14
15
This patch hardens the iothread_stop_all() approach by pausing vcpus
16
before calling iothread_stop_all().
17
18
Note that the assertion failure is a race condition. It is not possible
19
to reproduce it reliably.
