Okay, please don't do that in the future. The idea of the 'replies'
files is that they are captured from real qemu. I've currently modified
my qemu install to contain liburing so I'll post the updated ones.

I'll also drop any other hunks related to 'replies' in this patch when
I'll be pushing this.
