Support UKSM in CL kernel
I think it's would be useful if CloudLinux kernel contains UKSM (if it's really stable). There is a lot of same memory page in a LAMP+mail system, so I think it's can be very useful. (for example here is about 5-800 imapd process). Or any other really fast memory dedup modul also would be nice, but I didn't find other.

Due to the nature of single kernel systems UKSM is not needed in this case. Memory is shared by processes started from the same binary.

UKSM is really needed in hypervizor virtualization. All those imapd processes share code segment, and some other memory pages due to copy-on-write during fork.
So, there would be little if any memory benefit from UKSM, while it is pretty resource hungry.
