About the Kernel Patch Summaries

These summaries are written after each kernel release by examining the chunks of each patch file and figuring out what has changed. Occasionally, they are supplemented by notes that Linus (and others) posted to the linux-kernel mailing list.

The summaries from 2.2.0 onwards were put together by Myrdraal@deathsdoor.com -- originally appearing on the Cutting Edge Linux website.

New! Yaroslav Rosomakho is now also writing some kernel summaries, including pre-patches!

*Linux 2.2.6 patch - patch-2.2.6.gz (16-Apr-99)
    [Patch Browser]

*Linux 2.2.5 patch - patch-2.2.5.gz (29-Mar-99)
    [Patch Browser]


I made Linux-2.2.5 yesterday (as some people already have noticed: due to popular demand I try to delay the announcement for some time in order to let the thing percolate to mirror sites, in case anybody wondered).

The 2.2.5 release is meant to be a final cleanup release before I leave for a two-week vacation. So please take these release notes to also mean that it is probably a good idea to hold off emailing me stuff directly, unless it is a major bug that you really think I should look at immediately. I would suggest people discuss problems on the mailing list and on the newsgroups, where other competent people are, rather than expecting me to do much about it.

Also, note that there have been various indications that egcs potentially miscompiles the kernel, or at least makes some problems worse. We don't know whether that is due to one or more kernel bugs, compiler problems, or just combinations of "features" in both. I would suggest that if you have problems you at least verify whether the problems still exist with gcc-2.7.2.

That said, I bet that both the kernel people and the egcs people would be really happy the more people look into this - if somebody feels motivated enough and sees problems with egcs, it would be extremely powerful to try to pinpoint the particular file that seems to bring on the problems. I'm afraid it needs a known failure mode and lots of legwork to find out what triggers it, though.

Anyway, 2.2.5 does:

Have fun, because I will,

*Linux 2.2.4 patch - patch-2.2.4.gz (23-Mar-99)
    [Patch Browser]


There's a new 2.2.x version out there now.

As of 2.2.4, I shoul dbe synchronized with the Sparc[64] and PPC ports, which is the major reason why the patch is pretty huge. Apart from the architecture synchronizations, 2.2.4 does:

Most of the fixes aren't all that noticeable, but some of them can be showstoppers depending on whether you've ever seen them.

I hope to hear reports of the new kernel, and I'm going on a two-week vacation starting mid next week, so please give this a whirl.

*Linux 2.2.3 patch - patch-2.2.3.gz (08-Mar-99)
    [Patch Browser]

*Linux 2.2.2 patch - patch-2.2.2.gz (22-Feb-99)
    [Patch Browser]

Notes: Mostly nice bugfixes here. If you aren't having problems with 2.2.1, this is probably not a critical upgrade.


At about a week late due to various silly problems (davem crashed his disk with the TCP fixes on it etc), it's out there. Go and have fun,
