mm/khugepaged: convert __collapse_huge_page_isolate() to use folios
Patch series "Some khugepaged folio conversions", v3.
This patchset converts a number of functions to use folios. This cleans
up some khugepaged code and removes a large number of hidden
compound_head() calls.
This patch (of 5):
Replaces 11 calls to compound_head() with 1, and removes 1348 bytes of
kernel text.
