Subject: [Patch:000/005] wait_table and zonelist initializing for memory hotadd
Date: Tue, 11 Apr 2006 20:25:22 +0900 [thread overview]
Message-ID: <20060411202031.5643.Y-GOTO@jp.fujitsu.com> (raw)
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.
