+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)

      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
