Technical note added. If any revisions are required, please edit the "Technical Notes" field accordingly. All revisions will be proofread by the Engineering Content Services team. New Contents: Previously, an operation such as madvise(MADV_MERGEABLE) may have split VMAs (Virtual Memory Area) without checking if any huge page had to be split into regular pages, leading to huge pages to be still mapped in VMA ranges that would not be large enough to fit huge pages. With this update, huge pages are checked whether they have been split when any VMA is being truncated.
