Subject: Re: Add prefetch switch stack hook in scheduler function
Date: Wed, 27 Jul 2005 16:23:37 -0700 [thread overview]
Message-ID: <ed5aea4305072716233491f7f8@mail.gmail.com> (raw)
In-Reply-To: <20050727161316.0593d762.akpm@osdl.org>
Also, should this be called prefetch_stack() or perhaps even just
prefetch_task()? Not every architecture defines a switch_stack
structure.
