in the linux ,a one node (struct pglist_data) has many zone(struct
zone_struct),a zone has many page(struct page),is it right?
in the smp with adm64 with the hardware of numa, its linux is a smp os
,then there is only one node (struct pglist_data) in the os when running
or there are as many nodes as cpus in the system, does linux smp
support two or more nodes when running? or in this case linux support
numa feature?
I am confused
could you help me
Thanks in advance
