Centos ships in it's official repositories only rpm binaries built
from the content provided by RH. Those in [Base] and [Updates] try to be
identical replicas (modulo the usual trademarks/copyrights
modifications) while those from [Centosplus] enable several (to be read:
many) modules which are included but not enabled.
Any kernels which include other modifications, especially patches,
are provided by alternate channels and private repositories. Therefore
your patch cannot be included as such in Centos's kernels as long as
RHEL does not ship it either. However I guess that a reference to TOMOYO
and a link to the alternate repo could be added in the wiki, offering
an opt-in feature for the users who want it. What I am sure is that a
kernel which breaks ABI will never be part of the official repos, ABI
compliance for its entire lifespan is one of the core features of the

Well, you could use upstream's src rpm and/or correlate with Centos

Probably yours :)
