Would anyone be intrested (besides me) in a kernel which can page out certain parts of itself? The kernel should be in some kind of vmlinux-ish (as in: uncompressed) format on disk for on-demand re-loading of pages which are discarded. Certain parts of drivers could get the __pageable prefix or so (like the __init parts of drivers which get removed) for letting the paging-code know that it can be discared if memory-pressure demands it. __pageable -code would then be things like (e.g.!) the code which handles the open()/close() of a device. Most of the time a device spends more time doing read/write/ioctl then close/open so. Also; hopefully there's no interrupt-sensitive code in these routines. I would think is usable (for example) for my 8MB ram laptop. Anyone any thoughts on this?
