[uml-devel] Incremental patches available

[uml-devel] Incremental patches available

[Jeff Dike]

As part of my redoing how I work on UML, I've started using quilt to
maintain the changes going into a UML release as a set of discrete
patches.  Among other things, this lets me publish the patches that
have gone into my working tree before they are released as part of a
full UML patch.  See http://user-mode-linux.sourceforge.net/patches.html

There is one patch there, fixing something somewhat tangential (an
iomem bug exposed by the test suite, of which more later), letting me
figure out the new process.  This will be updated fairly frequently,
by cron or something.

This will greatly shrink the window in which someone can else find and
fix a bug, and send me a patch, while I, unbeknownst to anyone else,
have fixed the same bug.  Of course, this won't stop people who don't
look at that page, but at least the information is available.

It should also help UML stability by allowing people to test patches
between UML releases, so that they should be right by the time they
are released officially.

Finally, I'm going to have the release changelogs include the patches
that went into the release.  That will enable people who find some new
breakage to back out patches one by one until the breakage goes away.
A lot more people will be able to do useful debugging, since no
technical skills beyond running patch and rebuilding UML will be
required.

Well, just perfect! I'm very happy about this... Would you please to put there 
the splitout version of the patches beyond 2.4.24-1 (the one I already 
built and posted)?

Also, maybe you should add a -v# to the end of the name (since if a patch is 
buggy, you will maybe create a new version); you may prefer to add 
patchname-fix containing the changes, as Andrew Morton does, but in this case 
probably it is not very useful (it's easier than popping tons of patches and 
modifying one, especially if the fix comes from somebody else, but this is 
not our case).

Working on that.  First, I'm putting together a page about the UML test suite
to encourage people to use it and contribute to it.

Maybe, but I'd just as soon fix the broken patch.  In any case, my use of
quilt is only a day old, and I still have to figure out exactly how I'm
going to use it.
