| |
Hi.
These are patches for initialization of wait_table and updating of zonelists for memory hot-add. These patches can be used when a new node/zone becomes available. When empty zone becomes not empty by memory hot-add, wait_table must be initialized, and zonelists must be updated.
ex) x86-64 is good example of new zone addition. - System boot up with memory under 4G address. All of memory will be ZONE_DMA32. - Then hot-add over 4G memory. It becomes ZONE_NORMAL. But, wait table of zone normal is not initialized at this time.
This patch is for 2.6.17-rc1-mm2.
Please apply.
---------------------------- Change log from v1 of wait_table init and build_zonelist. - update for 2.6.17-rc1-mm2. - add comment for wait_table hash entries. - change name wait_table_size() -> wait_table_hash_nr_entries()
Change log from v4 of node hot-add. - wait_table and build_zonelists updating are picked up. - update for 2.6.17-rc1-mm1. - change allocation for wait_table from kmalloc() to vmalloc(). vmalloc() is enough for it.
V4 of post is here. <description> http://marc.theaimsgroup.com/?l=linux-mm&w=2&r=1&s=memory+hotplug+node+v.4&q=b <patches> http://marc.theaimsgroup.com/?l=linux-mm&w=2&r=1&s=memory+hotplug+node+v.4.&q=b
