Ask Slashdot: What Happens To -AC (And Other) Kernel Mods?

Aug 22, 2001, 23:48 (0 Talkback[s])

Alan Cox provides an explanation of how Linux kernel patches are handled in this edition of Ask Slashdot:

"Probably the first thing to explain is the Red Hat kernel. That actually isn't something I am responsible for. Arjan van de Ven is the keeper of the distribution kernel, and has the unenviable task of getting a kernel together that will actually pass all the brutal QA testing. Arjan is perfectly entitled to (and sometimes does) throw out bits of -ac changes.

You'll see Red Hat patches being merged into -ac and Linus trees when appropriate, often from Arjan or Pete Zaitcev. Many of the other patches in the RH tree are considered "fixups" - they are workarounds for problems but not generalised or clean enough to feed into the main tree without further work. Others are RH specific patches for things like packaging.

With the -ac tree I try and do rapid rolling releases, sucking in new code to test it and also its interactions with other new code. By doing releases every few days I get a high number of people testing and reporting bugs before there are too many possible causes. This is how Linus trees used to work long ago, and I still think its the better technique."
