From 039bc1240165c99b932fb4be2f784948d1038eea Mon Sep 17 00:00:00 2001 From: "Matthew Wilcox (Oracle)" Date: Thu, 12 May 2022 20:23:04 -0700 Subject: [PATCH] mm/swap: add folio_throttle_swaprate The only use of the page argument to cgroup_throttle_swaprate() is to get the node ID, and this will be the same for all pages in the folio, so just pass in the first page of the folio.
