From 0d648dd5c899f33154b98a6aef6e3dab0f4de613 Mon Sep 17 00:00:00 2001 From: Baolin Wang Date: Thu, 23 May 2024 10:36:39 +0800 Subject: mm: drop the 'anon_' prefix for swap-out mTHP counters The mTHP swap related counters: 'anon_swpout' and 'anon_swpout_fallback' are confusing with an 'anon_' prefix, since the shmem can swap out non-anonymous pages. So drop the 'anon_' prefix to keep consistent with the old swap counter names. This is needed in 6.10-rcX to avoid having an inconsistent ABI out in the field.
