about the worm feature

[Li, Dan]

Hi, all

I'd like to use vfs_worm modules to make a backup share for our storage system.
Except the grace period, I think it is better to add a retention period. 
A retention period means that during this period files are protected and immutable,
but over the period the files can be modified or deleted.

How about add this idea to add the options? 
Or should I create a new vfs module to implement this?


Regards,
Li Dan
