Cover letter [PATCH 00/10] AXFS: Advanced XIP filesystem
I'd like to get a first round of review on my AXFS filesystem. This is a simple read only compressed filesystem like Squashfs and cramfs. AXFS is special because it also allows for execute-in-place of your applications. It is a major improvement over the cramfs XIP patches that have been floating around for ages. The biggest improvement is in the way AXFS allows for each page to be XIP or not. First, a user collects information about which pages are accessed on a compressed image for each mmap()ed region from /proc/axfs/volume0. That 'profile' is used as an input to the image builder. The resulting image has only the relevant pages uncompressed and XIP. The result is smaller memory sizes and faster launches.
See http://axfs.sourceforge.net for more info.
