Subject: [patch 056/178] mm: memcontrol: fix kernel stack account
Date: Thu, 29 Apr 2021 22:56:02 -0700	[thread overview]
Message-ID: <20210430055602._TPiM7mzp%akpm@linux-foundation.org> (raw)
In-Reply-To: <20210429225251.02b6386d21b69255b4f6c163@linux-foundation.org>

From: Muchun Song <songmuchun@bytedance.com>
Subject: mm: memcontrol: fix kernel stack account

For simplification 991e7673859e ("mm: memcontrol: account kernel stack per
node") has changed the per zone vmalloc backed stack pages accounting to
per node.  By doing that we have lost a certain precision because those
pages might live in different NUMA nodes.  In the end NR_KERNEL_STACK_KB
exported to the userspace might be over estimated on some nodes while
underestimated on others.  But this is not a real world problem, just a
problem found by reading the code.  So there is no actual data to showing
how much impact it has on users.

This doesn't impose any real problem to correctnes of the kernel behavior
as the counter is not used for any internal processing but it can cause
some confusion to the userspace.

Address the problem by accounting each vmalloc backing page to its own
node.
