Subject: [PATCH 01/35] Replace __alloc_pages_internal() with __alloc_pages_nodemask()
Date: Mon, 16 Mar 2009 09:45:56 +0000	[thread overview]
Message-ID: <1237196790-7268-2-git-send-email-mel@csn.ul.ie> (raw)
In-Reply-To: <1237196790-7268-1-git-send-email-mel@csn.ul.ie>

__alloc_pages_internal is the core page allocator function but
essentially it is an alias of __alloc_pages_nodemask. Naming a publicly
available and exported function "internal" is also a big ugly. This
patch renames __alloc_pages_internal() to __alloc_pages_nodemask() and
deletes the old nodemask function.

Warning - This patch renames an exported symbol. No kernel driver is
affected by external drivers calling __alloc_pages_internal() should
change the call to __alloc_pages_nodemask() without any alteration of
parameters.
