I'm not sure that it leaves any confusion. It perhaps wastes a little space on 64bit architectures, but that also applies to a great deal of other bitmasks floating around. I can do it if you feel that passionate about it, but it's a bigger job to hunt down all occurrences and change them over. I only felt strongly enough about it to craft this patch because I noticed the inconsistency as I created new populate caps for OF functionality. -- Lee Jones Linaro ST-Ericsson Landing Team Lead Linaro.org ?
