From 30dac24e14b52e1787572d1d4e06eeabe8a63630 Mon Sep 17 00:00:00 2001 From: Pankaj Raghav Date: Thu, 26 Sep 2024 16:01:21 +0200 Subject: fs/writeback: convert wbc_account_cgroup_owner to take a folio Most of the callers of wbc_account_cgroup_owner() are converting a folio to page before calling the function. wbc_account_cgroup_owner() is converting the page back to a folio to call mem_cgroup_css_from_folio(). Convert wbc_account_cgroup_owner() to take a folio instead of a page, and convert all callers to pass a folio directly except f2fs. Convert the page to folio for all the callers from f2fs as they were the only callers calling wbc_account_cgroup_owner() with a page. As f2fs is already in the process of converting to folios, these call sites might also soon be calling wbc_account_cgroup_owner() with a folio directly in the future. No functional changes. Only compile tested.
