Ask New 2.4 Maintainer Marcelo Tosatti Anything 308

Posted by timothy
from the except-the-nude-beaches dept.
Linus keeps hinting (declaring, even) that he's nearly ready to work full-time on the 2.5 development branch of his kernel, and hand the 2.4 kernel off to Marcelo Tosatti. Marcelo's graciously agreeed to answer questions (you might want to read some of his mailing list contributions first), so here's your chance to ask him what he'll do in the famous footsteps of Linus and Alan Cox, and how he got there. Please only put one question per post; we'll pass along the top-rated comments to Marcelo for his answers, and hear back from him shortly.

    While linux has a tradition of giving stable kernels even subversions and unstable kernels odd subversions, the history of the 2.4 kernel has been far from stable so far.

    Wouldn't it make more sense to take 2.4.14 (or 2.4.15 whenever it comes out) and call that 2.5.0, while moving the unstable kernels over to 2.6? While it would break the even/odd numbering paradigm, that seems a better option than having a subversion which starts out unstable and partway through morphs into a stable form.

    Not having ALSA in 2.4.x means no good sound support in the stable kernel for another year of two. Do you plan to integrate ALSA into the 2.4 branch? If yes, will it happen after it's done on the 2.5 branch?

    Alan Cox's stand on the changelog is clearly not only a matter of personal protection, but a political statement. He has chosen an issue that is tremendously important to Linux, free software, and software developers everywhere, and certainly it's right for him to be pursuing it.

    But is the Linux kernel the right forum for politics? Do you feel that it's a bad idea to involve the kernel in politics -- a slippery slope in which the software itself becomes a political pawn? Or would you say that the kernel -- and all software -- has already become a political pawn, and Cox's actions are entirely justified given that free software's existence is under increasing threat?

  • by Zeio (325157) on Wednesday November 14, 2001 @01:35PM (#2564383)
    This is a mixed question/comment.

    What is going on here?

    It seems that Alan has stopped doing his -AC series...

    Linus is finishing up 2.4.X after making some deep changes to the VM (Adrea's new VM), and thankfully adding EXT3, but form what I have been reading, 2.4.15 is the end of the stable kernel series (with no XFS or JFS support which is upsetting).

    Andrea has a plethora of experimental/tweaked patches in ftp.kernel.org/pub/linux/kernel/people/andrea. What is interesting/worrisome to me is that Marcelo's directory there is empty.

    Marcelo must be a great guy, I've seen a lot of banter on newsgroups with him, and a few chages in the stable changelog here and there, but to me it looks like a lot of talk. Alan used to release (past tense, it seems it has stopped) AC patches on a near daily basis, to me, Marcelo is vapor.

    Is the maintainer's jobs simple to make small changes to the kernel when errata is found? Or is it, as Alan has done, to integrate and merge a LOT of stuff to produce a useful and robust hybrid kernel and then suggest that maybe the unbroken things should be merged in.

    I wish Marcelo luck in this endeavor, but also wish to see loads of "maintainence," Linux really, really needs feverish active development, and there a lot of people, Like Alan and Linus, who put out quite a bit. I am hoping Marcelo will set a new precedent for uber-feverish maintenance - maybe even see XFS and JFS and other things that the distributions have to waste huge amounts of time tinkering and adding various enterprise-ish things to make the Linux kernel stand up for, as they put it, prime time.
    • You are speaking of two separate things here. The first is that Alan Cox, among other things, is the maintainer of the 2.2.x series kernel. Maintainance entails fixing bugs, updating drivers, and possible backporting features from the next kernel series where determined to be appropriate. This is what Marcelo will be doing as maintainer.

      In addition to maitaining the 2.2.x series, Alan also has his own, more experimental tree knows as the -ac tree. This is where a lot of developers submit their patches for initial testing for a few reasons: Alan can get them in his tree sooner because his tree is more experimental than the main kernel tree; Alan is a direct link to Linus so if Alan approves of your patch, he will eventually submit it to Linus (all those merging comments in the kernel change logs).

      If you want to compare Marcelo's position to Alan's, your question would have to be, do you plan to start an -mt tree for the 2.6.x kernel series while maintaining the 2.4.x kernel?

    Would you consider using bitkeeper, cvs, or even complete changelogs with proper attribution of WHICH merges took place?

    Currently the Linux kernel is filled with functions that are either poorly documented or completely undocumented. One of the purported benefits of Free Software is that many developers can jump in and help yet when you have functions like __free_pages_ok [linux.no] in page_alloc.c that are important, complex yet the only comment is

    Buddy system. Hairy. You really aren't expected to understand this.


    doesn't this somehow defeat the point of the source being available in the first place? Basically the question I have to ask is this, "I have flirted with the thought of sending comment only patches to the kernel to further help people understand certain subtleties (e.g. why the pprev and next pointers in user_struct are not what they seem) in the source code especially CS students who are learning about the kernel in operating systems classes. If someone were to start such a program would such patches be accepted into the kernel?
    • Buddy system. Hairy. You really aren't expected to understand this.

      Heh. This is very similar to the comment in the original Unix sources. The idea was that it was completely obscure until one understood something magical that couldn't be documented, at which point it didn't need commenting. A lot of really low-level stuff can be pretty obscure and mind-bending - it's just a fact of life when dealing with such things and documenting it doesn't help.

      By the way, the Buddy System is a memory allocation strategy given by Donald Knuth in his book "Fundamental Algorithms". It's pretty obvious once you've seen how it works, but I'd have never thought of it independently. I would assume that understanding the code requires one to understand the algorithm first - e.g. by reading Knuth's excellent description that is unfortunately too long to stick in a comment.

    While I am a passionate Linux supporter, I have also come to the conclusion that kernel bloat is likely to be a major issue fairly soon. It appears to have been the case for some time that =486 systems Need Not Apply, and Red Hat in particular has become a rather memory-hungry distro (it won't even install on my 16MB Pentium system, though I doubt this is really a kernel issue). The end result is that Linux seems slowly to be growing out of the lower-end used-server-in-a-closet market that helped it get so big in the first place.

    My question: I presume kernel bloat, both in terms of code size and resource demands, can impact heavily on maintainability. Do you see this as a significant issue for the future, how much of a problem is it, and is it something that can be easily addressed without tearing apart the code base and reorganizing it from the ground up?

    /Brian
    • No, I shouldn't think it is. After all, you can just not compile in the stuff you don't want. By that method I keep my closetful of '486 servers running perfectly happily on recent kernels.
    • If you look at the growth of the kernel you'll see that the main parts have basically stayed the same size (in terms of lines of code) since 2.2.

      By the main parts I mean everything except drivers. The largest parts of this are the file system and network code. The file system grew a bit when Rieserfs was include into the kernel but it's a tiny increase compared to the rest of the code.

      Drivers make up more than 75% of the Linux source code. And this driver code is growing rapidly.

      People talk about the fact that you can cut things out of the Linux kernel if you don't want to use them. This is true. But it's even more true to say that if you did want to use everything in the Linux kernel you would have to buy a lot of hardware. :)

    One thing that is really missing is a list of changes in each kernel release that is meant to be consumed by the masses. The "changelogs" that are offered up are sorely lacking for us non-kernel hackers. What I'd like to see is a prose description of the changes in each version. Something like Release notes for 2.2.18 by Alan Cox [linux.org.uk] is a step in the right direction, but some of it is even a little too technical. For example, in the above document,

    set_current_state
    • Fixed potential SMP race
    means little to me and probably a lot of other people. Under what condition does this occur? The question why should I care about this change? should be answered for each entry.

    How does that weigh in on the todo scale versus my problem with the Visor driver? What if it was Connectiva that had the problem? (Or Redhat?)

    (and a quick second question: How can any human read teh 7000 posts a month to the mailing list and still get any coding done?)
  • Last I checked (which was a while ago), Linux kernels included only DRI support for XFree86 4.1, whereas Alan kernels included DRI support for both (or, rather one or the other, selected at compilation time). What will be the case with future official 2.4.x kernels?

    After the interview is all said and done. That's only ~10 questions. I'm seeing a lot more than 10 very important (IMHO) questions. Some of these questions being unanswered is a big contributor to why Linux is not so readily accepted in the corporate world.

    Where can we get the questions answered? I think that there ought to be a Linux kernel documentation project to bring the docs up to speed and answer questions like this. I have not the knowledge of the kernel for this, but such a project would be invaluable to the Linux community.

    Linus has stated that he'd like to get rid of a lot of the "non-informational" messages on boot and with this I have to agree with him.

    Do you plan on furthering this cause, and helping make our boot times a simpler, less complicated read?

    Marcelo,

    I must say that you are an amazing yet rare individual, to have commanded that much respect at the age of 18. Wow. I can't handle OS design now, let alone when I was 18. Would you be so kind as to share some about your upbringing, environment, faith, or other factors that were beneficial to you in making you who you are today?

    Thank you,

    Now that you are suddenly famous, do you see a lot of girls flocking to you yet?

    Do you intend to bend to popular demand for features at the price of stability or is stability king in the stable kernel ?

    I looked over some questions, and there are a couple of pretty obvious ones that either aren't their, or hidden due to that pesky moderation.

    For instance:
    1. The "lousy magazine"-question: Who would you rather be stuck with on a desert island?

    2. The "bitter old sysadmin"-question: You are 18, do you punk even know what Multics or VMS is?

    3. The "trick"-question: what do you prefer, emacs or vi? (trick question because we all know emacs is superior).

    Is Conectiva going to let you spend all your time to the 2.4 kernel?
    I read that you live in the same house as Rik van Riel, who wrote the first Linux 2.4 VM and who also works for Conectiva. Rik wrote in his not-that-very-often updated diary that he travelled a lot in Brazil, to help customers anywhere. That takes a lot of time. Is your job going to be different once Alan Cox passes the maintainership?

    Hi Marcelo,

    I have grown to respect quite a bit you as well as some of the other folks who work in kernel development at conectiva in Brazil (Rik, Arnaldo..).

    I have been wanting to try to read more and more about the linux kernel, and maybe(?) try to get involved, so i must ask how did you start out? Any pointers that i should follow to get to understand more deeply the kernel? I mean you are not in heavy kernel hacking and you are a few years younger than me... (My guess is that it wasnt in college, since by now you should be doing the infamous college entrance exams... aka vestibular =P)

    Also it seems that you value your privacy, since there isnt much public information about you out there... Would you elaborate a little on how you got where you are? =)

    Just one more thing... I feel i must say that all Brazilians and young people in general are very proud and happy to see where you are now! Thanks a lot and keep up the good work!

    Not that I wish to put you in an uncomfortable situation, but would it be possible to get your reaction to Eric S. Raymond's comment about the state of kernel development:

    "I've been examining the existing kernel configuration system, and I have about concluded that the best favor we could do everybody involved with it is to take it out behind the barn and shoot it through the head."

    For someone as persuasive and influential as Raymond to make such a statement, it begs for a response, if not a rebuttal.
  • Alan says: it is a great but academic project.
    linus says: Don't do drugs. (Or "i don't care")
    what is you opinion about this?
