Sagi,

Just wanted to give you an update on where we're at with this.

All tests run with your earlier patch removing the inline dispatch from
nvme_tcp_queue_request() are successful. At this point, I am leaning to
remove that optimization from mainline.

Thanks Keith,

Did you run it with the extra information debug patch I sent you? What
I'm concerned about is that given that you have the only environment
where this reproduces, and this is removed it will be very difficult
to add it back in.

Also, what about the read issue? that one is still unresolved from
my PoV.

The test team reports no issues for both read and write tests with the
inline dispatch removed. That single patch appears to resolve all
problems. Sorry, I should have clarified that initially.

We will go back to the extra debug from last week on top of a pristine
mainline kernel. There's been some confusion of which patches to apply
on top of others in the mix, but I'm getting better at coordinating
that.
