kdbus in the kernel

depontius,

How nice of them! They're going to leave linux users alone and can use they're own systemdOS.

It would be for the best if it wasn't a joke.

That would fix all the problems, for those that want they could run Pottering OS
and the rest of us could continue on with the linux we've known for a long time.

Hopefully what they will do next, is make it so only Red Hat can use systemd, forcing everyone that wants to use Gnome & systemd has to use Red Hat's distro, so everyone can finally forget about this trash and get on with having a system that actually works.

Phoronix counters that the systemd devs did not actually fork the linux kernel - that Ivan guy is not a systemd developer. http://www.phoronix.com/scan.php?page=news_item&px=Systemd-No-Linux-Fork

I'm curious if there's more to this - how often are mistakes like this made?

rofl - just found this https://github.com/systemdaemon/systemd/issues/1

edit: just saw this link was already put up in the politics of systemd thread

[split] chaff from kdbus in the kernel

Hrm, looks like it's going in: http://lkml.iu.edu/hypermail/linux/kernel/1503.3/00378.html

If it were me, I'd have it read "if you have an ordinary machine, choose N here"...

That is from two weeks ago, so nothing new just now. kdbus is in linux-next to receive more testing, but that doesn't mean it automatically goes into mainline.

Yeah nothing to worry about; just keep looking into my eyes, not around the eyes..
After all, it's not like anyone would dream of turning around later and saying "Well you had your chance; no-one responded to the 5th round of sales-pitch, so we put it in, you should have spoken back then" and other variants on "it's all your fault, suckers!"

Just deal with it, move on, etc; all the things we don't do, when we want to make y'all get in line.

I was merely preventing the thread from entering a sub-loop duplicating from this comment by repeating what Anon-E-moose had said himself. But if you disagree, go on!

I'm still seeing a couple of kernel devs who aren't too thrilled with kdbus as it is at the moment, so I doubt that it will go in until things get hammered out.

And again, just because it's up for review that does not mean automatic inclusion in the kernel

The biggest thing I've noticed is that some of the kernel devs have mentioned (several times)
that dbus could possibly be speeded up with a look at how it's implemented internally.

The *bus devs have been refusing to do this.

So it's obvious, at least to me, that they want kdbus in the kernel not for any real speedup but for other reason.
And yes, many of them have been brought up in these threads, ie bypassing the gpl, etc.

I doubt that I'm the only one that is seeing things this way.
And we've yet to hear Linus' view on kdbus.
Of course he may be waiting to see if it even makes muster, ie gets past the kernel devs with the NAKs.

Greg KH's pull request says kdbus has been in linux-next "for several months". This seems disingenuous to me. A quick check with Google, and it appears that the pull request for linux-next was around March 15, just under one month ago. The initial patches appear to have been first submitted back in October, about six months ago.

All else aside, does anyone know what the "average latency" is for a new large-ish feature to get added to the kernel? Six months from first patch actually seems kind of fast.

To be honest, I (sadly) expect kdbus to go in, maybe on 4.1, maybe on 4.2. I expect the real fireworks to happen when they expect to treat the kernel code with all of the stability of the rest of systemd. Come to think of it, I don't know how stable userspace dbus has been, if it's been more stable than the rest of systemd.
