The module does KABI tracking through weak-modules, so if it wasn't
compatible, it wouldn't add a link to it on the new kernel and someone
would need to recompile it for the newer kernel.
KABI tracking adds dependencies to kernel API by creating hashes of
the API prototypes and weak-modules compares those to the hashes of
the installed/installing kernel's API prototypes, if they match it
creates a link to the installed module under /lib/modules/<kver>/weak-
These KABI tracking modules. compiled on different kernel versions,
stick around after the kernel has been uninstalled, so don't remove
old /lib/modules directories without first making sure a KABI module
