Subject: [PATCH v3 0/2] btrfs: fix __folio_put refcount errors
Date: Tue, 2 Jul 2024 07:31:12 -0700 [thread overview]
Message-ID: <cover.1719930430.git.boris@bur.io> (raw)
Switching from __free_page to __folio_put introduced a bug because
__free_page called put_page_testzero while __folio_put does not. Fix the
two affected callers by changing to folio_put which does call
put_folio_testzero.
