From: Oscar Salvador <[email protected]> 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.
