From: Oscar Salvador <osalvador@xxxxxxx>
Hi,
I this is a small cleanup for the memhotplug's code.
A lot more could be done, but it is better to start somewhere.
I tried to unify/remove duplicated code.
The following is what this patchset does:
1) add_memory_resource() has code to allocate a node in case it was offline.
Since try_online_node has some code for that as well, I just made add_memory_resource() to
use that so we can remove duplicated code..
This is better explained in patch 1/4.
2) register_mem_sect_under_node() will be called only from link_mem_sections()
3) Make register_mem_sect_under_node() a callback of walk_memory_range()
4) Drop unnecessary checks from register_mem_sect_under_node()
I have done some tests and I could not see anything broken because of
this patchset.
