It already says: "To disable them, pass "transparent_hugepage=never" to the kernel in your bootloader (grub, lilo, etc.)."The page https://mariadb.com/kb/en/mariadb/documentation/storage-engines/tokudb/how-to-enable-tokudb-in-mariadb/
.. should have added for SuSE"YAST2 -> Bootloader -> Kernel Parameters. Add transparent_hugepage=never to Optional Kernel Command Line Parameter at the end, like after "showopts" and press OK. And you're done. It'll take effect on the next reboot."
(according to the reply I had here https://forums.opensuse.org/showthread.php/503373-How-to-disable-Transparent-Hugepages?p=2681756#post2681756 - I have not tried yet myself).
