This shrinks the text segment on an amd64 kernel by ~32k, data by ~6k, bss by ~33k, overall ~72K memory saved. I'm not going to apply this, sorry Andi. I want the freedom to use the XFRM layer for generic things at some point.
But in 2.7 surely right? When what happens you can easily make CONFIG_XFRM the default. This would give the 2.6 users an useful option. Also when you do use it generically you will hopefully discard some old code (like the rt cache?) which may make up for the additional bloat. But until that happens having both even when not needed doesn't make too much sense.
How about working on making the xfrm layer more lean instead? :)
My last proposal for this (using hlists in the hash tables) was rejected, so I don't see much chance to do this. -Andi
