Hi Fengguang,

Is this boot test also run on my bbrezillon-0day/nand/layering-rework
branch (before merging it into devel-spot), and if it is, do you see the
same error?

Is the devel-spot-201512102358 tag publicly accessible? If it's not,
could you push it somewhere (or give me a way to generate it by
pulling the relevant branches), so that I can investigate on this bug?

Okay. You mean linux-next/master alone, or after merging my branch into
linux-next/master?

I had a quick look at the changes made in my patchset, and I didn't
find any obvious errors. I'll try to test the nandsim driver tomorrow.

BTW, the backtrace looks a bit weird to me, it mixes nandsim functions
(ns_init_module()) with diskonchip functions (inftl_scan_bbt()), which,
AFAIK, is not supposed to happen.

Thanks,

Boris

The bisect tests bbrezillon-0day/nand/layering-rework, however it's
fine there.

Nope.

Or it may be more convenient to check linux-next first?

It's stand alone linux-next/master as indicated by the bisect log.
Does it include any of your patches?

I tried to boot the next-20151214 build, before [1] and after [2]

I'll try to recreate your devel-spot locally and see if I can reproduce
the bug.

Are you using the emailed kconfig? I'd not recommend try the below
step if cannot even reproduce the issue in linux-next.

Yes, I did use the config you attached in your email + the script your
pasted to boot the kernel with qemu, and linux-next/master boots
correctly.
As answered in the other email I just sent, I managed to reproduce the
bug you're pointing after merging both
bbrezillon-0day/nand/ecclayout-squashed and
bbrezillon-0day/nand/layering-rework into linus' 4.4-rc4.

FYI, below is the patch I used to fix the bug, but I'd be interested in
reproducing the problem you've seen on linux-next/master. Did you, by
any chance, keep the branch/tag you used to trigger this bug on
linux-next?

Yes. Bisect log shows that these 2 commits both have the bug:

# extra tests on tree/branch linus/master
git bisect  bad a80c47daa818ead2644917d72ff2a934dd64fd16  # 03:36      0-      1  Merge tag 'sound-4.4-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
# extra tests on tree/branch linux-next/master

Okay, I think I found the problem: you're pulling
bbrezillon-0day/nand/ecclayout-squashed and then
bbrezillon-0day/nand/layering-rework. Those branches are both based on
Brian's l2-mtd/master branch, and are both changing NAND subsystem
internals. IOW, the changes brought by nand/ecclayout-squashed are
introducing new "mtd->priv" occurrences, while the goal of
nand/layering-rework is to replace them by mtd_to_nand(mtd) and kill
the mtd->priv = xxx assignments, hence the NULL pointer exception.

I guess I'm the one responsible for this false positive, because I
pushed two non-independent branches in my 0day tree.
I could rebase my nand/ecclayout-squashed branch and fix all the faulty
places, but that implies reordering your pull commands
(nand/layering-rework before nand/ecclayout-squashed). Would that work
for you? Any other suggestions to gracefully handle this kind of
dependencies?

Best Regards,

Boris

Ah got it, sorry for the noises!

There is no much to do about such dependencies. One possible fix is to
improve the 0day system to bisect the conflicting merges, which should
save the lots of manual efforts to locate the problem. I've put it as
a TODO item.

Okay, I think I'll temporary kill the nand/ecclayout-squashed branch
until I've properly rebased it on top of the nand/layering-rework one,
so that you can still tests changes coming from other trees.
