Re: [PATCH v2] staging: erofs: use explicit unsigned int type

[Gao Xiang]

Hi Thomas,

Thanks for your new patch.

It seems that this patch also introduces 2 new 'WARNING: line over 80 characters',
could you please fix it in the patch?

It will be better to fix that.

Some reviewed cleanup patches are merged before this patch, then I failed to add
this one, so could you rebase on top of erofs dev branch in below link:

https://git.kernel.org/pub/scm/linux/kernel/git/chao/linux.git/log/?h=erofs

[PATCH] MAINTAINERS: add tree location for staging/erofs

@Chao,Gao: For some reason there seems to be a problem when receiving mails
from you. The one I received now was the first one from you that reached me
directly. Before I only got your messages in the quotes from Dan and now in the
quotes from the mail I am responding to.
(I will try to investigate the reason for this)

Sorry for my slow responses before.

> It will be better to fix that.

A new patch will shortly follow.

I was not aware of this tree and worked off of staging / next.
A patch is attached to this message that adds the tree to the MAINTAINERS file.

Currently this location is not documented.

Hi Chao,

I think this tree has some PREVIEW patches which preview in linux-erofs mailing list only and
doesn't send to staging mailing list and LKML,

https://git.kernel.org/pub/scm/linux/kernel/git/chao/linux.git/log/?h=erofs

so erofs tree is actually Greg's staging tree.

Hi Thomas,
nope, the erofs tree is actually the same as staging tree, so any patch should be based
on Greg's upstream tree.

Thanks,

Correctly or not, have you tried it?

Thomas,

I confirmed that erofs git repository for linux upstream is Greg's staging tree.

Let me explain, in order to avoid sending buggy or preview patch, Xiang and me
plan to review patches in erofs mailing list first, and then cache reviewed
patches in my git tree before sending them to Greg and staging mailing list.

Based on that, I'm trying to serialize all erofs patches, expecting that can
help those patches sent to staging mailing list can be merged by Greg with
lesser conflict. But I made a mistake that my erofs branch has merged some
pending patches, result in failing to merge yours, that mislead me to ask you to
rebase the code, sorry about that.

Now I can confirm that your v2 patch can apply on Greg's staging-next, so fixing
warning reported by checkpatch.pl on your v2 patch is enough. :)

Thanks,

As Chao's said, we keep on fetching the latest Greg's staging tree and develop
, preview, and test new erofs features and bugfix based on it.

For the cleanup patches, it could be better directly based on Greg's upstream
staging tree. We will then rebase our developping code on your work. :)

Yes, we are sorry about that. could you please send v4 patch which follows Greg's
and Chao's suggestions?

Thanks,
Gao Xiang

The patch was supposed to be applied with "git am --scissors".
To be honest, I am not sure if the scissors feature of git is to be used for
kernel development, or if I should have announced it.
If is not applicable I will be happy to resend the patch in another format.

The documentation for git-mailinfo(1) sounded it would fit my usecase perfectly:

   ...
   This is useful if you want to begin your message in a discussion thread with comments and suggestions on the message you are responding to, and to conclude it with a
   patch submission, separating the discussion and the beginning of the proposed commit log message with a scissors line.
   ...

> Correctly or not, have you tried it?

I tried to both apply and compile the patch, both succeeded.

Thank you for clearing this up! And I am sorry for causing you all this work
for what is essentially a very small style cleanup.

> Now I can confirm that your v2 patch can apply on Greg's staging-next, so fixing

The patch follows.

Thomas


Changes since v1:

* Removed changes that conflicted with
  [PATCH 1/6] staging: erofs: formatting fix in unzip_vle_lz4.c
* Added patch description

Changes since v2:

* Fixed conflicts with other patchsets
* Don't introduce new style issues

Changes since v3:

* Fixed conflicts with other patchsets

Note: This patchset should be applied with the "git am --scissors", to
remove the historic information and this note.

-- >8 --

Fix coding style issue "Prefer 'unsigned int' to bare use of 'unsigned'"
detected by checkpatch.pl.
