A preliminary development version of ext4 was included in version 2.6.19[4] of
the Linux kernel. On 11 October 2008, the patches that mark ext4 as stable code
were merged in the Linux 2.6.28 source code repositories,[5] denoting the end of
the development phase and recommending ext4 adoption. Kernel 2.6.28, containing
the ext4 filesystem, was finally released on 25 December 2008

CentOS5.5 has the 2.6.18.* kernel so doesn't support ext4
