Subject: [rfc 00/10] [RFC] Page flags: Saving some, making handling easier etc. Newsgroups: gmane.linux.kernel Date: 2008-03-01 04:05:34 GMT (17 weeks, 6 days, 17 hours and 36 minutes ago) 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. -- |
