@smaslov-intel, are the fails related to the change? |

@kbsmith-intel, @pvchupin : I was able to reproduce the hang in https://github.com/intel/llvm-test-suite/blob/intel/SYCL/InorderQueue/in_order_usm_explicit.cpp. There are 3 memcpy submitted into the in-order queue there (all in there own command-lists) and synchronizing the last memcpy's event never finishes. Nothing jumped out at me by just looking at traces, needs debugging. I consider this being of low priority (and may be even drop it altogether) since a L0 driver complete fix is ready. |

If that was a workaround and real fix is ready feel free to abandon the change, unless @kbsmith-intel see any value I'm missing... |
