I'd like to reference a paper titled "FASS : A Flash-Aware Swap System".
(http://kernel.kaist.ac.kr/~jinsoo/publication/iwssps05.pdf)
The paper describes a technique that uses NAND flash as a swap device
without FTL (Flash Translation Layer) or filesystem.
It is not related with XIP, however.

All right. I'll try to make an important face whenever the subject
comes up.

So what you mean is "swap on flash" ? Defintively sounds like an
interesting topic, although I'm not too sure it's all that
filesystem-related.
Maybe not. Yet, it would be a very useful place to store data from a
file as a non-volatile page cache.
Also it is something that I believe would bene

I wouldn't want to call it swap, as this carries with it block-io
connotations. It's really mmap on flash.
Yes

Yes, it basically needs an ftl.

Do we have any data preferences yet?

A few things I'd like to talk about are:
- the address space operations APIs, and their page based nature. I think
it would be nice to generally move toward offset,length based ones as
much as possible because it should give more efficiency and flexibility
in the filesystem.

I'd just like to take the chance also to ask about a VM/FS meetup some

I was thinking about trying to arrange a proper mini summit thing, but
it's a bit difficult and we could talk this year about doing it for
subsequent year
