Thanks Jason for feedback.
Can you be more specific about "the invalidation model for MR was wrong"
MR's must be invalidated before data is handed over to the block
layer. It can't leave MRs open for access and then touch the memory
the MR covers.
Jason is referring to these fixes:
2f122e4f5107 ("nvme-rdma: wait for local invalidation before completing
a request")
4af7f7ff92a4 ("nvme-rdma: don't complete requests before a send work
request has completed")
b4b591c87f2b ("nvme-rdma: don't suppress send completions")
