[PATCH V2 0/3] Refine numa_emulation

From: Wei Yang
Date: Tue May 02 2017 - 09:05:19 EST

My previous patch "x86/mm/numa: Remove numa_nodemask_from_meminfo()" hits a
problem in numa_emulation. The reason is numa_nodes_parsed is not set
correctly after emulation.

This patch set tries to fix this and also with two code refine.

Detailed discussions are in this thread:


and test result is posted :


* refresh the change log based on David comments
* use nodes_clear()

Wei Yang (3):
x86/numa_emulation: fix potential memory leak
x86/numa_emulation: assign physnode_mask directly from
x86/numa_emulation: restructures numa_nodes_parsed from emulated nodes
