CentOS 6 is around for quite some time and they provide kernel 2.6.32. I know the vendor versions differ from the ones. Since vanilla kernel 2.6.33 and onwards provide trim support, I wonder if CentOS 6 kernels has this backported?

CentOS is made from the opensource RHEL 6 sources from Red Hat. Red Hat has backported the trim support for SSD into the RHEL kernel.
