The purpose of this cleanup is to identify bdrv_aio_cancel() as an API
that does not work with the multi-queue block layer.

When I backport patches into RHEL, the general process I follow is:
1. For context conflicts, just adjust the patch to resolve them.
2. For real dependencies, backport the dependencies, if possible.
3. If backporting the dependencies is not possible, think of a
downstream-only solution. This

Or instead of using linker behavior, maybe just change the #ifdef so it
only applies when KVM is disabled. I didn't look at the code to see if this
is possible, but it would be nice to avoid the very specific #ifdef
condition in this patch.

Another approach is a static library with a .o file containing the
stubs so the linker only includes it in the executable if the compiler
emitted the symbols. That way there is no need for defined(__clang__)
&& !defined(__OPTIMIZE__) and it will work with other
compilers/optimization levels. It's more work to set up though.

This patch refactors the HMP monitor to use the existing event loop
instead of creating a nested event loop. This will allow the next
patches to rely on draining call_rcu work.

call_drain_rcu() has limitations that make it unsuitable for use in
qmp_device_add(). Introduce a new coroutine version of drain_call_rcu()
with the same functionality but that does not drop the BQL. The next
patch will use it to fix qmp_device_add().

Fixes: 7bed89958bfbf40df9ca681cefbdca63abdde39d ("device_core: use

qapi/qdev.json
evice_add() into a coroutine monitor command and uses
drain_call_rcu_co().
I'm sending this as an RFC because I don't have confirmation yet that the bugs
mentioned above are fixed by this patch series.
Stefan Hajnoczi (3):
hmp: avoid the nested event loop in handle_hmp_command()
rcu: add drain_call_rcu_co()
