Hey,
Check the comments in these files:
/* * hugepage-mmap: * * Example of using huge page memory in a user application using the mmap * system call.
/* * hugepage-shm: * * Example of using huge page memory in a user application using Sys V shared * memory system calls. In this example the app is requesting 256MB of * memory that is backed by huge pages. The application uses the flag * SHM_HUGETLB in the shmget system call to inform the kernel that it is * requesting huge pages.
/* * Example of using hugepage memory in a user application using the mmap * system call with MAP_HUGETLB flag.
All of them are examples, not tests, not tools, thus Documentation/ is the best place for them.
