about the worm feature

[Li, Dan]

Hi, 

Thanks for your suggestion!

I can add a new module named "worml" for short of "worm limit" which has the retention period.
I'd like to implement it based on the code of vfs_worm and vfs_readonly.

I know that 'worm' has a common meaning in storage for ages, 
but I think the meaning is changing because the evolution of the media of storage.
For example, Glusterfs and NetApp has its worm feature with the retention period.

Anyway, can I just contribute my patch and how should I do that?

Regards,
Li Dan
