* Compressed Cache System -- Implement NetBSD version of compressed cache system (for low-memory devices): http://linuxcompressed.sourceforge.net/ The complete list of project ideas is available online at http://www.netbsd.org/contrib/projects.html
Just so I actually have some answers for my proposal, I was wondering if I could get some feedback here.
I was thinking of implementing this (a compressed cache for UVM) as a patchset for UVM, as I feel that a kernel option to turn this on and off would be a little 'icky' (for lack of a better word), _especially_ for people who don't care about this option.
Also, a question I've been thinking about, some compressed cache systems only store pages that are backed by files and not swap-backed pages. What is the communities view on this? The research from http://linuxcompressed.sourceforge.net/ shows that good results can still be achieved even if the compressed cache stores swap-backed pages.
Wondering if people have any opinions on the merits of both approaches? Thanks, Matt
