Subject: [PATCH 01/15] RPC/RDMA: refactor the inline memory registration code.
Date: Wed, 08 Oct 2008 11:47:03 -0400 [thread overview]
Message-ID: <20081008154703.1336.69063.stgit@tmt3.nane.netapp.com> (raw)
In-Reply-To: <20081008154506.1336.59892.stgit-pfX4bTJKMULWwzOYslWYilaTQe2KTcn/@public.gmane.org>
Refactor the memory registration and deregistration routines.
This saves stack space, makes the code more readable and prepares
to add the new FRMR registration methods.
