In my first try to fix 20212 I didn't reproduce bug on required kernel (6.9.2) and wrongly concluded that first two completions have different order on newer kernel.
On my current kernel (6.5.0) order of completions is: send1, recv, send2. On 6.9.2 order is send1, send2, recv. This fix allows second two completions to arrive in any order.
Tested on both kernels.
