Subject: Re: [PATCH] scripts: gtags_files_generator.sh

Hi, greg

I'm really sorry for the bad reply i did, i even don't know what was my email problem ..

I mean i'm very new to git-send-email related, very very confused about the email processing..

Please help me understanding where my problem is, I am very serious in organizing this

submission related email, even every sentence written in the email.

Did i filled the wrong msg-id in --in-reply-to? Or i should directly answer your question by following

format, just like your reply:

        > make defconfig
        > make
        > scripts/gtags_files_generator.sh
        > gtags [-f gtags.files]
        >
        > Enjoy with vim+gtags. :)

        What's wrong with just 'make gtags' that we currently have in the kernel
        tree?  Shouldn't that be sufficient, and if not, then you need to
        explain why it isn't in your changelog.

How do you add '>' before this lines, all by hands?

If I did something wrong, please help me to know it, (oh, my poor english ..)

Thanks! :(

As this is a new version, you need to properly version your patch, as is
documented, please do that.

Also, you seem to be ignoring my previous questions/comments, which
makes me want to just ignore this patch :(
