- Users of CIP SLTS kernels with extreme service life that may involve not upgrading until after y2038 (this is obviously not recommended if you connect to a public network, but I'm sure some people do this anyway). For running user space, this requires either a 32-bit kernel with the linux-5.1 syscall changes or a 64-bit kernel. If you run a 64-bit linux-4.9 kernel in a deeply embedded non-networked machine, it still makes sense to have working inode timestamps and be able to test that.

CIP is currently aiming for a 10 year support lifetime, so both of its currently existing branches (4.4, 4.19) should be long out of support in 2038. Still, it's possible that some people hope to extend that later.
