Subject: [PATCH] mm/khugepaged: make khugepaged_collapse_control static

Make khugepaged_collapse_control as it is not exported.
Fixes the following sparse warning:

mm/khugepaged.c:829:25: warning: symbol 'khugepaged_collapse_control' was not declared. Should it be static?

Fixes: 34d6b470ab9cf ("mm/khugepaged: add struct collapse_control")
