[Devel] [PATCH VZ10 2/2] mm/memcontrol: drop mappedtodisk from cache folio flag sanity check

[Pavel Tikhomirov]

PG_mappedtodisk is a normal flag for file page cache folios, so it does
not belong in the WARN_ON listing flags incompatible with a cache charge.

https://virtuozzo.atlassian.net/browse/VSTOR-134021
Fixes: 0ad1e82744aba ("mm: Memory cgroup page cache limit")
Feature: mm: Memory cgroup page cache limit
