Hi Linus,
Please consider pulling the XArray patch set. The XArray provides an
improved interface to the radix tree data structure, providing locking
as part of the API, specifying GFP flags at allocation time, eliminating
preloading, less re-walking the tree, more efficient iterations and not
exposing RCU-protected pointers to its users.
This patch set introduces the XArray implementation and converts the
pagecache over to use it. The page cache is the most complex and
important user of the radix tree, so converting it was most important.
I have followup patches to convert the other users of the radix tree
over to the XArray, but that'll be another hundred or so patches and I
want to get this part in first.
There are two conflicts I wanted to flag; the first is against the
linux-nvdimm tree. I rebased on top of one of the branches that went
into that tree, so if you pull my tree before linux-nvdimm, you'll get
fifteen commits I've had no involvement with.
The other is a fairly trivial one with ext4. I've incorporated the
change from Ross that Ted merged into that tree into my tree, so please
take the resolution in my tree.

So this merge window has been horrible, but I was just about to start
looking at it.
And no. I'm not going to pull this.
For some unfathomable reason, you have based it on the libnvdimm tree.
I don't understand at all wjhy you did that.
That libnvdimm tree didn't get merged., because it had complete
garbage in the mm/ code. And yes, that buggy shit was what you based
the radix tree code on.
I seriously have no idea why you have based it on some unstable random
tree in the first place.
But basing it on something that I independently refused to pull
because of obvious bugs from just a quick scan - that completely
invalidates this pull request.
Why?
I guess it makes this merge window easier, since now I don't even have
to look at the code, but it annoys the hell out of me when things like
that happen.
There wasn't even a mention in the pull request about how this was all
based on some libnvdimm code that hadn't been merged yet.
But you must have known that, since you must have explicitly done the
pull request not against my tree, but against the bogus base branch.
And since I won't be merging this, I clearly won't be merging your
other pull request that depended on this either.
Why the f*ck were these features so interlinked to begin with?

I said in the pull request ...
There are two conflicts I wanted to flag; the first is against the
linux-nvdimm tree. I rebased on top of one of the branches that went
into that tree, so if you pull my tree before linux-nvdimm, you'll get
fifteen commits I've had no involvement with.
Dan asked me to do that so that his commit (which I had no involvement
with) would be easier to backport. At the time I thought this was a
reasonable request; I know this API change is disruptive and I wanted
to accommodate that. I didn't know his patch was "complete garbage";
I didn't review it.
So, should I have based just on your tree and sent you a description of
what a resolved conflict should look like?

I can yank most of the patches (all but the last two, iirc) out of the
IDA patchset and submit those as a separate pull request. Would that
be acceptable? I'm really struggling to juggle all the pieces here to
get them merged.

Absolutely.
Or preferably not rebasing at all, just starting from a good solid
base for new development in the first place.
Sometimes you start from the wrong point, and decide that you really
need to rebase, but then you should rebase to a more stable point, not
on top of some random independent development.
Rebasing can be a really good tool to clean up development that was
haphazard - maybe as you go along you notice that something you did
earlier turned out to be counter-productive, so you rebase and clean
up your history that has not been made public yet.
But when you send me a big new feature, the absolutely *last* thing I
want to ever see is to see it based on some random unstable base.
And rebasing to avoid merge conflicts is *always* the wrong thing to
do, unless the reason you're rebasing is "hey, I wrote this feature
ages ago, I need to really refresh it to a more modern and stable
kernel, so I'll rebase it onto the current last release instead, so
that I have a good starting point".
And even then the basic reason is not so much that there were
conflicts, but that you just want your series to make more sense on
its own, and not have one horribly complex merge that is just due to
the fact that it was based on something ancient.
The absolute last thing I want to see during the merge window is
multiple independent features that have been tied together just
because they are rebased on top of each other.
Because that means - as in this case - that if one branch has
problems, it now affects all of them.
Merge conflicts aren't bad. In 99% of all cases, the conflict is
trivial to solve. And the cost of trying to deal with them with
rebasing is much much higher.

Ah, I remember now, it was more complex than a textual conflict.
Dan added an entirely new function here:
http://git.infradead.org/users/willy/linux-dax.git/commitdiff/c2a7d2a115525d3501d38e23d24875a79a07e15e
which needed to be converted to XArray. So I should have pulled in his
branch as a merge somewhere close to the end of my series, then done a
fresh patch on top of that to convert it?
It would have been pretty ugly because he modified a function I deleted.
I might try it out just to show how bad it would have been.

No, it doesn't matter if you rebase on top of a broken branch, or you
merge it in. Either way, it's broken and I can't merge your end
result.
You should simply NOT CARE about other branches. Particularly not
other branches that might not even get merged in the first place!
You should care about *YOUR* work. You should make sure *your* work
is rock solid, and that it is based on a rock solid base. Not some
random shifting quick-sand of somebody elses development branch.
Sure, then linux-next will give a merge conflict, but at that point
YOU DO NOT REBASE OR MERGE. You tell linux-next how to merge it, and
mention it to me in the pull request.
Because at that point, I have the *choice* of merging just one of the
branches or both. Or I can merge them in either order, and test them
independently?
See how that is fundamentally different from you tying the two
branches together and handing me a fait accompli?
Yes, yes, sometimes you have to tie branches together because one
branch fundamentally depends on the features the other branch offers.
But that should be avoided like a plague if at all possible.
And it damn well isn't an issue for something like xarray, which has a
life entirely independently of libnvdimm (and vice versa), and the
conflict was just random happenstance, not some "my changes
fundamentally rely on the new features you provide".

That was partly my fault for giving not very good advice when the
(quite complex) merge conflict turned up in the linux-next tree. I
will try to give better advice in the future.

Is this going in this cycle? I have a bunch of stuff on top of this to

No.
It was based on a buggy branch that isn't getting pulled, so when I
started looking at it, the pull request was rejected before I got much
further.

To be clear, I don't think the problem you identified can be triggered
in practice. We are under the equivalent of the page lock for dax in
that path, and if ->mapping is NULL we would bail before finding that
the mapping-size helper returns zero.

For the record I think skipping the entirety of the libnvdimm pull
request for this cycle due to that misuse of ilog2() is overkill, but
it's not my kernel.
Andrew, I think this means we need to lean on you to merge
dax-memory-failure and Xarray for 4.20 rather than try to coordinate
our own git branches for these specific topics.
At a minimum for 4.19 I think we should disable MADV_HWPOISON for dax
mappings this cycle to at least close that trivial method to crash the
kernel when using dax.
Dave, I recommend dropping dax-memory-failure and sending the other
libnvdimm topics for 4.19 that have been soaking in -next.
