  tested: add test for nested aio_poll() in poll handlers (2023-05-17 18:01:22 +0200)

----------------------------------------------------------------
Block layer patches

- qcow2 spec: Rename "zlib" compression to "deflate"
- Honour graph read lock even in the main thread + prerequisite fixes
- aio-posix: do not nest poll handlers (fixes infinite recursion)
- Refactor QMP blockdev transactions
- iotests/245: Check if 'compress' driver is available

----------------------------------------------------------------
Akihiro Suda (1):
      docs/interop/qcow2.txt: fix description about "zlib" clusters

Kevin Wolf (9):
      block: Call .bdrv_co_create(_opts) unlocked
      block/export: Fix null pointer dereference in error path
      qcow2: Unlock the graph in qcow2_do_open() where necessary
      qemu-img: Take graph lock more selectively
      test-bdrv-drain: Take graph lock more selectively
      test-bdrv-drain: Call bdrv_co_unref() in coroutine context
      blockjob: Adhere to rate limit even when reentered early
      graph-lock: Honour read locks even in the main thread
      iotests/245: Check if 'compress' driver is available

Stefan Hajnoczi (2):
      aio-posix: do not nest poll handlers
      tested: add test for nested aio_poll() in poll handlers

Vladimir Sementsov-Ogievskiy (6):
      blockdev: refactor transaction to use Transaction API
      blockdev: transactions: rename some things
      blockdev: qmp_transaction: refactor loop to classic for
      blockdev: transaction: refactor handling transaction properties
