The latest -ac patch to the stable Linux kernels

The latest -ac patch to the stable Linux kernels

[Adam McKenna]

finger@finger.kernel.org reports the following:

The latest stable version of the Linux kernel is:           2.4.18

But,

The latest -ac patch to the stable Linux kernels is:        2.4.19-pre5-ac3

These seem somewhat contradictory..  Shouldn't the second one report
2.4.18-ac3?

Not at all.

Alan's most recent patch is in line with the 2.4.19 series of patches, 
these are pre patches to the upcoming 2.4.19.

Regardless.  Alan is free to name his patches however he wants.

all the -ac kernels need to be treated as -pre

if you watch in detail you can pick ones that are more likly to be stable
then others, but some of them will be intentionally cutting edge.

Exactly.

Alan does have a track record of stable kernels, but his tree does have
quite a lot of experimental patches in it.  He does warn about patches that
could be quite bad though (think ide and the recent suspend patches).

In fact, I'm using some -ac kernels in production after it has survived on
my workstation for a while and there haven't been any bug reports for the
stuff I use...

Also, 2.4.18 is the first time that I've seen Alan have -ac patches directly
against 2.4.xx instead of 2.4.xx-pre.  Unless he says otherwise I wouldn't
expect that to happen again.

Well, shortly put, the -ac tree is much more -pre than the -pre patches 
are.  Using -ac patches is jumping ahead of the -pre patches normally.

  At one point Alan posted "I actually run my kernels" and I think that's
important. In some cases they contain perfectly stable features which are
not in the mainline for... I don't want to say "political reasons," but
reasons of policy rather than technical issues. I have run production on
rmap and O(1) for a while, but they seem destined to stay in 2.5 near
term.

  The -ac has the new ServerRAID driver from IBM. Since I have systems
using the hardware which are timezones away, anything which tends to
stability is good in my use. New firmware means new drivers (often) and
the IBM update CD has a binary module only. I'll try the pre5-ac3 instead.

People like you shouldn't use -ac. It is even slightly more experimental than 
-pre. Wait for non-pre or take the risk of -pre[-ac].

As I understand it there is only one "latest -ac": the one against latest 
-pre.

I was under the impression that the -ac line has a bunch of VM fixes that
haven't been merged into the main tree yet, which should make it better under
high loads than the standard kernel.

Is this no longer the case?

It is, except that the changes currently in -ac are more
suitable to be merged into 2.5 first ;)
