Initiator side eh_abort goes through a specific IOCB call "Abort IO" that can

Joe,
How do I get access to this specific Ubuntu kernel where the bug is found? Is
there stack trace/bug report that you could share? Any data would be helpful.
Thanks.
In the mean time, I will download 4.5 rc4 to re-verify.

At this point we can forgo this patch to stable tree. There are
additional tweaks in this path during testing. We will update the stable
