I updated to 4.8rc6 and my FIO test that had previously failed with the Linux NVMeF target (using null_blk device as the target) is now completing successfully. I am still seeing the same NAK (Remote Access Error) failure when I use our target instead. I will debug this further but updating to 4.8rc6 did improve things.

Hi Narayan,

I also saw similar error with 8k write when I use my own target implementation.
Did you fix it already?
