* remotes/stefanha/tags/block-pull-request:
  block: Factor out bdrv_run_co()
  exec: Rename qemu_ram_writeback() as qemu_ram_msync()
  hw/block: Let the NVMe emulated device be target-agnostic
  memory: Extract memory_region_msync() from memory_region_writeback()
  memory: Rename memory_region_do_writeback -> memory_region_writeback
  fuzz: run the main-loop in fork-server process
  fuzz: add mangled object name to linker script
  fuzz: fix typo in i440fx-qtest-reboot arguments
  fuzz: add datadir for oss-fuzz compatability
  io_uring: use io_uring_cq_ready() to check for ready cqes
  io_uring: retry io_uring_submit() if it fails with errno=EINTR
