Despite the concerns that I mentioned, an x86 guest booted up and ran fio benchmarks fine in various configurations (aio=threads/native/io_uring, iothread on/off).

[PATCH v5 0/4] AioContext removal: LinuxAioState and ThreadPool
Just remove some AioContext lock in LinuxAioState and ThreadPool. Not related to anything specific, so I decided to send it as a separate patch. These patches are taken from Paolo's old draft series. --- v5: * apply Stefan comments, add patch 4 to remove ThreadPool * param from thread_pool_submit* * document that functions run in current IOThread v4: * add missing aio_context removal, and fix typo v3: * remove qemu_coroutine_enter_if_inactive v2: * assertion in thread_pool * remove useless BlockDriverState * param in patch 1 and 2 * io_uring cleaned too Emanuele Giuseppe Esposito (4): linux-aio: use LinuxAioState from the running thread io_uring: use LuringState from the running thread thread-pool: use ThreadPool from the running thread thread-pool: avoid passing the pool parameter every time include/block/aio.h | 8 -- include/block/raw-aio.h | 33 --- include/block/thread-pool.h | 15 ++- include/sysemu/block-backend-io.h | 6 + backends/tpm/tpm_backend.c| 4 +-- block/file-posix.c| 45 --- block/file-win32.c| 4 +-- block/io_uring.c | 23 ++-- block/linux-aio.c | 29 +++- block/qcow2-threads.c | 3 +-- hw/9pfs/coth.c| 3 +-- hw/ppc/spapr_nvdimm.c | 6 ++--- hw/virtio/virtio-pmem.c | 3 +-- scsi/pr-manager.c | 3 +-- scsi/qemu-pr-helper.c | 3 +-- tests/unit/test-thread-pool.c | 12 - util/thread-pool.c| 25 + 17 files changed, 113 insertions(+), 112 deletions(-) -- 2.39.1
