Revision be458311cdbb5d94820ffc4e40c5906085c0a507 authored by Roman Gushchin on 01 October 2020, 20:07:49 UTC, committed by Linus Torvalds on 02 October 2020, 16:13:41 UTC
Since commit ea426c2a7de8 ("mm: memcg: prepare for byte-sized vmstat
items") the write side of slab counters accepts a value in bytes and
converts it to pages. It happens in __mod_node_page_state().
However a non-SMP version of __mod_node_page_state() doesn't perform
this conversion. It leads to incorrect (unrealistically high) slab
counters values. Fix this by adding a similar conversion to the non-SMP
version of __mod_node_page_state().
