I believe you can look through the RHEL tech notes. Here they are for
6.5:
https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html-single/6.5_Technical_Notes/index.html
If you require barriers, you can always use the mainline kernel from
elrepo. You can read about the mainline and long-term packages here:
http://elrepo.org/tiki/kernel-lt
You probably want the kernel-ml packages, but that page doesn't mention
the -lt packages. Lots of CentOS admins use these kernels (including
me) and are happy with them.
