LTS 5.15 EOL Date

LTS 5.15 EOL Date

[Suleiman Souhlal]

Hello,

I saw that the projected EOL of LTS 5.15 is Oct 2023.
How likely is it that the date will be extended? I'm guessing it's
pretty likely, given that Android uses it.

Thanks,
-- Suleiman

Android is the only user that has talked to me about this kernel
version so far.  Please see:
	http://kroah.com/log/blog/2021/02/03/helping-out-with-lts-kernel-releases/
for what I require in order to keep an LTS kernel going longer than 2
years.

If your group at Google is going to rely on this kernel version, please
read the above link and talk to me about it.

thanks,

Yes, we are going to rely on this kernel version.
I know Guenter (cced) has done (and is still doing) testing on -rc
versions, but if more is needed I'm sure we can find a way.

Microsoft is also interested in a longer lifetime for v5.15 LTS. An
additional year should meet our needs.

We are aware of your "Helping Out ..." blog post and have been making
improvements to be of more assistance. Kelsey and Allen (Cc'ed) have
been doing -rc testing of v5.15 -rc releases and reporting the results
to the list, on behalf of Microsoft. Testing of the -rc releases is
mostly manual at this point, so we don't get every release tested before
the release happens, but we're working on improving our processes and
having builds/tests kick off automatically so that you can rely on us
even more. We should have a much better system in place to help with
testing and reporting by the time Oct 2023 rolls around. :)

Let us know if there's anything else that we can do to help.

Wonderful, thanks for letting us know.

Don't you all use kernelci already?  Doesn't that fit into your testing
environment already to make this easier?

And yes, I have seen the testing results, thank you for that.  If you
all want to be added to the initial -rc1 email announcement to help
trigger any build systems that way, just let me know.

thanks,

You're right that we provide kernelci resources for the broader
community but we use something different internally.

Thanks. I had planned to watch for new pushes to the linux-stable-rc.git
branches. If that doesn't work for some reason, we'll take you up on the
email offer.

Watch out when using that tree, it is rebased all the time and contains
intermediate steps before the "real" -rc releases happen.  It is there
for systems that can not handle quilt series.

good luck!
