Stefan Hajnoczi 9f8d2fdcce aio: remove aio_context_acquire()/aio_context_release() API ... Delete these functions because nothing calls these functions anymore. I introduced these APIs in commit 98563fc3ec ("aio: add aio_context_acquire() and aio_context_release()") in 2014. It's with a sigh of relief that I delete these APIs almost 10 years later. Thanks to Paolo Bonzini's vision for multi-queue QEMU, we got an understanding of where the code needed to go in order to remove the limitations that the original dataplane and the IOThread/AioContext approach that followed it. Emanuele Giuseppe Esposito had the splendid determination to convert large parts of the codebase so that they no longer needed the AioContext lock. This was a painstaking process, both in the actual code changes required and the iterations of code review that Emanuele eked out of Kevin and me over many months. Kevin Wolf tackled multitudes of graph locking conversions to protect in-flight I/O from run-time changes to the block graph as well as the clang Thread Safety Analysis annotations that allow the compiler to check whether the graph lock is being used correctly. And me, well, I'm just here to add some pizzazz to the QEMU multi-queue block layer :). Thank you to everyone who helped with this effort, including Eric Blake, code reviewer extraordinaire, and others who I've forgotten to mention.
