[$] Two talks on multi-size transparent huge page performance

Description:
Using huge pages has been known for years to improve the performance of
many workloads. But traditional huge pages, often sized by the CPU at 2MB,
can be difficult to allocate and can waste memory due to internal fragmentation. Driven by both the folio transition and hardware
improvements, attention to smaller, multi-size transparent huge pages
(mTHPs) has been on the rise. In two memory-management-track sessions at
the 2024 Linux Storage,
Filesystem, Memory-Management and BPF Summit , developers discussed the kernel's ability to reliably allocate mTHPs and the performance gains that result.
