I regularly forget, then look at the code, then get it wrong. That's for mainline, let alone older kernels whose behaviour is gawd-knows-what. So... For the changelog (and the manpage) could we please have a full description of the 2.6.21 behaviour and the 2.6.21-post-rik behaviour (and the 2.4 behaviour, if it differs at all)? Also some code comments to demystify all of this once and for all?
