Rebased on the current nvme/nvme-6.8 branch and added the Review tags. Also
addressed the printk format issue pointed out by Chaitanya.

About PI: I've added a note to the first commit pointing on this topic. I
understood from the discussion, that yes it is an issue but it already exists
and we will address this in future.

Thanks,
Daniel

Thanks, added to nvme-6.8.

I'm rebasing my fixes to the PI bug (which are not trivial) on top of 
nvme-6.8 and Daniel's series.
I've found that this branch is missing some fixes from the master that 
I've added manually to local nvme-6.8 branch.
When do you plan to rebase the nvme-6.8 on top of master ?
It will be helpful, otherwise my patches will not apply cleanly on your 
branch. :)

-Max.

linux-nvme pulls go through Jens' linux-block repo, so we have to be
based on the appropriate branch from there. We already have some late
fixes in 6.7 that create minor merge conflicts for our existing 6.8
branch, so we may provide a reference resolution branch with the pull
request if conflicts are non-trivial. That might be an option for your
fixes if you can make them work atop existing nvme-6.8 without the
conflicting 6.7 changes.

Sometime after the next merge window opens, Jens will rebase his 6.8
block tree to Linus', and we usually get a 2nd feature pull request
within the merge window from that new baseline. That might be an option
if you want to wait a couple more weeks.

I see. I think that after finishing the latest testing I'll send the 
version on top of nvme-6.8 + my local branch patches I took from 6.7.
We will start the reviewing process and probably will converge in a week 
or two. Then we will see what is the status of the linux-block repo and 
decide how to continue.
