v2: * Add missing backtrace in Patch 3 It's possible to hit the "Co-routine re-entered recursively" error with -drive format=qcow2,aio=native. This is a regression introduced by a linux-aio.c optimization. See Patch 3 for details.
Patches 1 & 2 add a new coroutine API called qemu_coroutine_entered() for checking whether a coroutine is currently "entered". This makes it possible to avoid re-entering coroutines recursively.
