Hi,
Greg KH has communicated a few times before on his blog [1] that he is
seeking the help of individuals and company to help him maintain the
LTS kernels and allow them to be made 6 years instead of just the
usual 2 years.
5.10 is a 6 year LTS, but 5.15 is not listed as such, although it
certainly would make sense for it to be since we use 5.15 in OpenWrt.
It would be good for the project to have a designated contact who can
communicate the kernel version plan ahead of time, or once a LTS is
picked up, we could sign up people to do regular testing of the stable
release candidates?
Thoughts?

Hi Florian,
I saw that you are often testing the stable rc version, this is really
great. Someone could try to automate this in OpenWrt to automatically
test the stable RC kernel versions, but it probably still needs some
maintenance. Currently I do not see that we have the resources to do this.
Yes I do try to test the release candidates when they show up, although
that is done on the limited set of devices I have at work and at home
usually, so it won't catch all of the possible regressions, and the
tests are limited to kselftests and some occasional one offs that are
device specific.
I do not think OpenWrt needs 6 LTS years kernel support 3 to 4 years is
fine for OpenWrt. If we do the 22.03 stable release in the next week we
can declare 21.02 end of life by end of February 2023. We would have
used kernel 5.4 only a bit over 3 years after its initial release is
November 2019.
OK, the 3-4 years time frame is not something that we currently have
with Linux kernels, it is either 2 years or 6 years, since 6 > 4, it
sounds like we still have some interest in having 6 LTS kernels, but
maybe not have every single LTS release be 6 years, right?
If you want to volunteer to help Greg KH more on this it would still be
nice.
I will continue to help with the stable candidates testing for the
foreseeable future as it is largely automated and does not require much
effort on my side, and will keep an open channel with Greg to tell him
about what OpenWrt has selected.
