These few patches are the result of a random hacking I did to make the qemu cope with eventfd allocation failure, when using an iothread, as it happened in bz #1897550.I am not 100% sure which patches in this series are worth to merge, or if this can be fixed in a better way. After this patch series applied, qemu still hangs while running reproducer for this BZ due to ABBA lock inversion which needs some heavy rework to get rid of. I explained all the (gory) details in the bugzilla. This patch series was (lightly) tested with make check, iotests and with the reproducer.
