Subject: [rfc 00/10] [RFC] Page flags: Saving some, making handling easier etc.
Date: Fri, 29 Feb 2008 20:05:34 -0800	[thread overview]
Message-ID: <20080301040534.797979115@sgi.com> (raw)

A set of patches that attempts to improve page flag handling. First of all a
method is introduces to generate the page flag functions using macros. Then
the number of page flags used by sparsemem is reduced.

Then we add a way to export enum constant to the preprocessor which allows
us to get rid of __ZONE_COUNT and use the NR_PAGEFLAGS for the calculation
of actually available page flags for fields.

Lastly there is a land grab of page flags for various ongoing VM projects.
