Well, this is like "echo madvise > /sys/kernel/mm/transparent_hugepage/enabled"
But I don't see how to set never.
# CONFIG_TRANSPARENT_HUGEPAGE_ALWAYS is not set
# CONFIG_TRANSPARENT_HUGEPAGE_MADVISE is not set
But I don't known how to unset CONFIG_TRANSPARENT_HUGEPAGE_ALWAYS in the new pve-kernel package makefile ?
I have tried to add
-d CONFIG_TRANSPARENT_HUGEPAGE_ALWAYS \
but it don't seem to work, I still have CONFIG_TRANSPARENT_HUGEPAGE_ALWAYS=Y in .config
Any idea ?

I could set it in kernel config, for example:
would that help?
