From 37f08dda29dac8a595999b8d3eaa9bf0f763dd9d Mon Sep 17 00:00:00 2001 From: Vladimir Davydov Date: Thu, 14 Jan 2016 15:18:18 -0800 Subject: [PATCH] vmalloc: allow to account vmalloc to memcg Make vmalloc family functions allocate vmalloc area pages with alloc_kmem_pages so that if __GFP_ACCOUNT is set they will be accounted to memcg. This is needed, at least, to account alloc_fdmem allocations.
