Subject: Re: [PATCH] 2.6.23-rc6: Fix NUMA Memory Policy Reference Counting
Date: Tue, 18 Sep 2007 00:28:19 +0200 [thread overview]
Message-ID: <200709180028.19462.ak@suse.de> (raw)
In-Reply-To: <1190057534.5460.131.camel@localhost>
> Handling policy ref counts for hugepages is a bit trickier.
> huge_zonelist() returns a zone list that might come from a
> shared or vma 'BIND policy. In this case, we should hold the
> reference until after the huge page allocation in
> dequeue_hugepage(). The patch modifies huge_zonelist() to
> return a pointer to the mempolicy if it needs to be unref'd
> after allocation.
