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: https://lkml.org/lkml/2017/3/13/1230 and test result is posted : https://lkml.org/lkml/2017/4/10/641 V2: * 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 numa_nodes_parsed x86/numa_emulation: restructures numa_nodes_parsed from emulated nodes arch/x86/mm/numa_emulation.c | 61 ++++++++++++++++++++++++-------------------- 1 file changed, 33 insertions(+), 28 deletions(-) -- 2.11.0
