Subject: mm: pagevec: add folio_batch_reinit()
Date: Thu, 12 Jan 2023 12:39:28 +0000
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.
