Re: [lustre-discuss] build help with 5.15 kernel
Hello Michael
Lustre 2.12.8 does not support Linux 5.15
More recent Lustre versions support up to Linux 5.11 but not further.
See these tickets for 5.12 and 5.14 support.
https://jira.whamcloud.com/browse/LU-14651
https://jira.whamcloud.com/browse/LU-15220
It is possible to manually backport patches to support some 5.x kernels with
2.12 but this is not trivial.
I don't know what is your current project but it will be much easier for you if
you can target an older Linux kernel and focus on kernel used by major distro.
Ubuntu 20.04 is using 5.11 by example.

Some additional info. I extracted the make command and ran it against the 2
kernel versions. Old kernel works, new kernel fails

I'm trying to build the Lustre 2.12.8 client on a 5.15 kernel and already
