Documentation/vm/transhuge.txt: add information about max_ptes_swap
max_ptes_swap specifies how many pages can be brought in from swap when
collapsing a group of pages into a transparent huge page.
/sys/kernel/mm/transparent_hugepage/khugepaged/max_ptes_swap
A higher value can cause excessive swap IO and waste memory. A lower
value can prevent THPs from being collapsed, resulting fewer pages being
collapsed into THPs, and lower memory access performance.
