Hi Luigi, All the pointers to code or the HOWTO will be assuming you are using the latest stable release. The HOWTO, starting on line 369, explains how to use the feature. If you simply want to dive into the code to see how it is done, the elflink.c file is the place to start. The entry point into this file is hugetlbfs_setup_elflink() which is called from init.c. Please post any questions you have about segment remapping, most of the folks who have ever worked on this library are still lurking and odds are good someone here will be able to handle your questions.
