Linux内核告别2.6进入3.0新时代 [转]

Godbach

在Linus Torvalds发布第一版Linux内核将近20年，历经39个2.6内核主版本之后，Linux之父刚刚通过了Linux 3.0的发布。Linux内核3.0目前已经在RC1阶段。
Torvalds在当地时间下午6点左右将93MB的Linux内核3.0 RC1下载包发布到了kernel.org的邮件列表上。

　　虽然版本号的大改变看起来非常令人振奋，不过在Git上签出代码的批注上，Linus 表示，3.0 版本只是数字上的改变而已。随后的官方声明上Torvalds则表示，除了例常的六成驱动更新和一些补丁修复之外，3.0版本没啥特别的，不会改变 ABI，不会改变 API ，也不会添加任何另人激动及兴奋的新功能。

　　3.0中可能的一些改进包括添加 EXT4 和 Btrfs 文件系统的 Cleancache 支持，添加 Microsoft Kinect Linux 驱动支持，以及各种开源图形驱动的改善。

　　Linus Torvalds的通告邮件参见LWN。

　　虽然Torvalds说的这么低调，但不知大家是否仍然会期待一些惊喜？

呵呵。前天看过。
曾经有人提议将2.6内核发展到2.6.40后在升级到3.0，但是linus并没有采纳。

记得最初计划是搞 2.8，现在直接上 3.0 了

1. 
   
2. Yay! Let the bikeshed painting discussions about version numbering
   
3. begin (or at least re-start).
   
4. 
   
5. I decided to just bite the bullet, and call the next version 3.0. It
   
6. will get released close enough to the 20-year mark, which is excuse
   
7. enough for me, although honestly, the real reason is just that I can
   
8. no longe rcomfortably count as high as 40.
   
9. 
   
10. The whole renumbering was discussed at last years Kernel Summit, and
    
11. there was a plan to take it up this year too. But let's face it -
    
12. what's the point of being in charge if you can't pick the bike shed
    
13. color without holding a referendum on it? So I'm just going all
    
14. alpha-male, and just renumbering it. You'll like it.
    
15. 
    
16. Now, my alpha-maleness sadly does not actually extend to all the
    
17. scripts and Makefile rules, so the kernel is fighting back, and is
    
18. calling itself 3.0.0-rc1. We'll have the usual 6-7 weeks to wrestle it
    
19. into submission, and get scripts etc cleaned up, and the final release
    
20. should be just "3.0". The -stable team can use the third number for
    
21. their versioning.
    
22. 
    
23. So what are the big changes?
    
24. 
    
25. NOTHING. Absolutely nothing. Sure, we have the usual two thirds driver
    
26. changes, and a lot of random fixes, but the point is that 3.0 is
    
27. *just* about renumbering, we are very much *not* doing a KDE-4 or a
    
28. Gnome-3 here. No breakage, no special scary new features, nothing at
    
29. all like that. We've been doing time-based releases for many years
    
30. now, this is in no way about features. If you want an excuse for the
    
31. renumbering, you really should look at the time-based one ("20 years")
    
32. instead.
    
33. 
    
34. So no ABI changes, no API changes, no magical new features - just
    
35. steady plodding progress. In addition to the driver changes (and the
    
36. bulk really is driver updates), we've had some nice VFS cleanups,
    
37. various VM fixes, some nice initial ARM consolidation (yay!) and in
    
38. general this is supposed to be a fairly normal release cycle. The
    
39. merge window was a few days shorter than usual, but if that ends up
    
40. meaning a smaller release and a nice stable 3.0 release, that is all
    
41. good. There's absolutely no reason to aim for the traditional ".0"
    
42. problems that so many projects have.
    
43. 
    
44. In fact, I think that in addition to the shorter merge window, I'm
    
45. also considering make this one of my "Linus is being a difficult
    
46. ^&^hole" releases, where I really want to be pretty strict about what
    
47. I pull during the stabilization window. Part of that is that I'm going
    
48. to be traveling next week with a slow atom laptop, so you had better
    
49. convince me I *really* want to pull from you, because that thing
    
50. really is not the most impressive piece of hardware ever built. It
    
51. does the "git" workflow quite well, but let's just say that compiling
    
52. the kernel is not quite the user experience I've gotten used to.
    
53. 
    
54. So be nice to me, and send me only really important fixes. And let's
    
55. make sure we really make the next release not just an all new shiny
    
56. number, but a good kernel too.
    
57. 
    
58. Ok?
    
59. 
    
60. Go forth and test,
    
61. 
    
62.                            Linus

hacker不都是喜欢搞一点幽默
linus这次有点逊掉耶~改版本没给点惊喜
