The application requests this itself from the Kernel. See https://man7.org/linux/man-pages/man2/mlock.2.html

From the link, mlockall with MCL_CURRENT | MCL_FUTURE

> Lock all pages which are currently mapped into the address space of the process.

> Lock all pages which will become mapped into the address space of the process in the future.
