Hi all,
After merging the staging tree, today's linux-next build (x86_64
allmodconfig) produced this warning:
In file included from include/trace/events/erofs.h:8,
from <command-line>:
include/trace/events/erofs.h:28:37: warning: 'struct dentry' declared inside parameter list will not be visible outside of this definition or declaration

Introduced by commit
47e4937a4a7c ("erofs: move erofs out of staging")
(or, at least, exposed by it). It needs, at least, a "struct dentry;"
added to the file.

Odd, why has this never been seen before when the same files were in
drivers/staging/ and why 0-day isn't reporting this?
Gao, can you send me a patch for this?

I Think it is weird since it is never failed in staging and kbuild-all 0-day ci
(my tree and you tree)....

Got it, I will look into that...

Could you give me more log about this? I don't know how to reproduce that warning
since I can compile x86-64 kernel image with my configproperly on my PC...
I'm trying allmodconfig now...

I have tested the latest staging-next tree with x86_64 allmodconfig with
https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git
the following commands (on my x86-64 PC),
$ make allmodconfig
$ make -j12
and it compiles successful as below:
LD [M] sound/usb/hiface/snd-usb-hiface.ko
LD [M] sound/usb/line6/snd-usb-line6.ko
LD [M] sound/usb/line6/snd-usb-pod.ko
LD [M] sound/usb/line6/snd-usb-podhd.ko
LD [M] sound/usb/line6/snd-usb-toneport.ko
LD [M] sound/usb/line6/snd-usb-variax.ko
LD [M] sound/usb/misc/snd-ua101.ko
LD [M] sound/usb/snd-usb-audio.ko
LD [M] sound/usb/snd-usbmidi-lib.ko
LD [M] sound/usb/usx2y/snd-usb-us122l.ko
LD [M] sound/usb/usx2y/snd-usb-usx2y.ko
LD [M] sound/x86/snd-hdmi-lpe-audio.ko
LD [M] sound/xen/snd_xen_front.ko
LD [M] virt/lib/irqbypass.ko
g00380047@architecture4:~/oss/linux-staging$
I'm also testing the latest linux-next tree with commit 47e4937a4a7c applied,
git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
and the command is the same (on my x86-64 PC),
$ make allmodconfig
$ make -j12
it seems all .o in fs/erofs have been generated properly, although the final
result hasn't been generated. I will reply the final result later...
Out of curiosity, are there some merge conflicts raised? Or could you give
me some hints (code and .config) to reproduce that? since I don't find any
potential issue in include/trace/events/erofs.h and fs/erofs/*... I have no
idea what happened and how to do next... Thank you very much!

The attempt above compiles successfully as well... And I have tried
the following commands (Just in case...) and the result turns out
without any difference...
$ make ARCH=x86_64 allmodconfig
$ make ARCH=x86_64 -j16
and I'm so confused now... Hope to get your hints...

I think I got the warning now... Sorry, I thought it is a compile error.
I am looking into that, sorry about that...
