@maksfb  I think the full solution is to check READ_ONLY_THP_FOR_FS option in /boot/config-xxx file.
Depends on the option state and kernel version we can call munlock & madvise or hugifyForOldKernel function.
I wouldn’t want to add extra options, if you agree with this implementation I can prepare the patch, what do you think?
