From 92d0510c3585970fb26af27f7fd3ba58321523ac Mon Sep 17 00:00:00 2001 From: Roman Gushchin Date: Wed, 1 Apr 2020 21:06:49 -0700 Subject: mm: kmem: switch to nr_pages in (__)memcg_kmem_charge_memcg() These functions are charging the given number of kernel pages to the given memory cgroup. The number doesn't have to be a power of two. Let's make them to take the unsigned int nr_pages as an argument instead of the page order. It makes them look consistent with the corresponding uncharge functions and functions like: mem_cgroup_charge_skmem(memcg, nr_pages).
