The kernel’s hugetlbfs
subsystem was the first mechanism by which the kernel made huge pages
available to user space; it was added to the 2.5.46 development kernel in
2002. While hugetlbfs remains useful, it is also viewed as a sort of
second memory-management subsystem that would be best unified with the rest
of the kernel. At the 2024 Linux Storage,
Filesystem, Memory-Management and BPF Summit, Peter Xu raised the
question of what that unification would involve and what the first steps
might be.
