Subject: mm: pagevec: add folio_batch_reinit()
Date: Thu, 22 Dec 2022 19:48:30 +0000
Patch series "update mlock to use folios".
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, 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 4):
This performs the same task as pagevec_reinit(), only modifying a folio
batch rather than a pagevec.
