So as promised, I tried to test your series. Your github branch [1]
'reg_api.3' though mostly has 4.3-rc1 contents, it isn't
based of 4.3-rc1 so I just cherry picked the patches and created
'rdma/sagi/reg_api.3_cherrypick' [2]. I had conflict with iser
patch so I just dropped that one.
As mentioned earlier, I have a WIP RDS fastreg branch [3]
which is functional (at least I can RDMA messages across
nodes ;-)). So merging [2] and [3], I created [4] and applied
a delta change based on your other patches. I saw ib_post_send
failure with my HCA driver returning '-EINVAL'. I didn't
debug it further but at least opcode and num_sge were set
correctly so I shouldn't have seen it. So I did memset()
on reg_wr which seems to have helped to fix the ib_post_send()
failure.
But I got into remote access errors which tells me that I
have messed up setup(rkey, sge setup or access flags)
or missing some other patch(s) in my test tree[4]. Delta
patch is top commit on [4].
Please let me know if you spot something which I missed.
Regards,
Santosh
