It seems that you tried to patch the CentOS kernel and it didn't work. A patch
for a newer kernel probably wouldn't apply clean, and the CentOS kernels
coming from RHEL are heavily patched already. The last time I played in the
kernel there were at least a hundred patches. Probably more. Any one of those
could contribute to your new patch failing.
I usually wouldn't recommend using a non-standard kernel on CentOS. If the
kernel in the main repo or the plus repo doesn't suit your system, and you add
a kernel from the main kernel.org sources, you risk de-stabilizing your
system. An Enterprise linux like CentOS is designed for stability and long
life and the pieces are fairly intertwined. If you need a custom patch or a
newer kernel, I would just use a distribution like Gentoo or Slackware that
seems to use newer parts, or see if someone already adds your patch to their
MailScanner is like deodorant...
You hope everybody uses it, and
you notice quickly if they don't!!!!
