pramfs: persistent and protected RAM Filesystem

Hi all,

after a lot of improvement, test, bug fix and new features, it's the moment for third round with the kernel community to submit PRAMFS for mainline.

Since the last review (June 2009) a lot of things are changed:

- removed any reference of BKL
- fixed the endianess for the fs layout
- added support for extended attributes, ACLs and security labels
- moved out any pte manipulations from fs and inserted them in mm
- implemented the new truncate convention
- fixed problems with 64bit archs

...and much more. Complete "story" in the ChangeLog inserted in the documentation file.

In addition, in the web site tech page (http:\\pramfs.sourceforge.net), you can find a lot of information about implementation, technical details, benchmarking and so on.

All the work to mainline this feature is sponsored by the CE Linux Forum.

Regards,
Marco
