Subject: proc: convert clear_refs_pte_range to use a folio
Date: Tue, 2 Apr 2024 21:12:48 +0100
Patch series "Remove page_idle and page_young wrappers".
There are only a couple of places left using the page wrappers for idle &
young tracking. Convert the two users in proc and then we can remove the
wrappers. That enables the further simplification of autogenerating the
definitions when CONFIG_PAGE_IDLE_FLAG is disabled.
This patch (of 4):
Replaces four calls to compound_head() with two.
