Subject: [Patch 000/002](memory hotplug) Rearrange notifier of memory hotplug (take 2)
Date: Thu, 18 Oct 2007 12:20:38 +0900 [thread overview]
Message-ID: <20071018120343.5146.Y-GOTO@jp.fujitsu.com> (raw)
Hello.
This patch set is to rearrange event notifier for memory hotplug,
because the old notifier has some defects. For example, there is no
information like new memory's pfn and # of pages for callback functions.
Fortunately, nothing uses this notifier so far, there is no impact by
this change. (SLUB will use this after this patch set to make
kmem_cache_node structure).
In addition, descriptions of notifer is added to memory hotplug
document.
This patch was a part of patch set to make kmem_cache_node of SLUB
to avoid panic of memory online. But, I think this change becomes
not only for SLUB but also for others. So, I extracted this from it.
This patch set is for 2.6.23-mm1.
I tested this patch on my ia64 box.
Please apply.
Bye.
