PRAMFS status update

Hi all,

the goal of this email is to update all about the mainlining activity of pramfs. In the last review (patch series v5) I didn't receive any comments so maybe I can hope for the next merge window. Meanwhile I fixed something and added support for others, here a list:

- added support for fallocate
- added support for splice
- added ioctl operations for inode flags management
- improved allocation strategy in direct io path
- fixed the return value management of pram_iget function

I created a git repo for the code:

git clone git://pramfs.git.sourceforge.net/gitroot/pramfs/pramfs

Regards,

Marco
