Difference between Kernel 7.22 and 7.22_EXT

Hi Team,

We need to perform Upgrade on our Netweaver 7.0 dual stack system to Netweaver 7.31 dual stack.

I saw we have Options to choose kernel as 7.22 and 7.22_EXT.

Both Kernels have same release date so not sure which one I should go and what is difference between Kernel 7.22 and 7.22_EXT.

Please suggest what is difference between these kernel and which one we should go for our upgrade target.

Regards,
