mm: pagevec: add folio_batch_reinit()
Patch series "update mlock to use folios", v4. This series updates mlock to use folios, converting the internal interface to using folios exclusively and exposing the folio interface externally. As a product of this we move to using a folio batch rather than a pagevec for mlock folios, which brings it in line with the core folio batches contained in mm/swap.c. This patch (of 5): This performs the same task as pagevec_reinit(), only modifying a folio batch rather than a pagevec.
