Subject: [RFC PATCH 0/4] async: fix hangs on weakly-ordered architectures
Date: Mon, 6 Apr 2020 15:13:16 -0400 [thread overview]
Message-ID: <20200406191320.13371-1-pbonzini@redhat.com> (raw)
Patch 4 fixes qemu-img and qemu-io hangs on weakly-ordered architectures.
Patch 1-3 are related docs fixes and improvements.
This is RFC because it relies on the iothread being locked during aio_poll
on the main AioContext. If I add assertions for this however I see a
failure for test 267, so I am posting it as a preview before I debug that.
The doc patches can also go in independently of course.
