Re: [GSoC 2013] Implement file system flags to scrub data blocks before deletion

#tech-kern, I need your help.
I have updated the repository [1] (moving to cvs soon).
Most of current details are in the README.

First of all, I'd love to hear any comments and/or suggestions.
Second, I am seeking volunteers to build and test the patch.

Next, I ran into an issue when trying to send a DIOCACHESYNC ioctl to a vnd.
The lwp hangs, probably trying to obtain some lock taken previously,
but that's just my guess.
I might be doing something wrong, if anyone has clues, please help.

Finally, I was looking for some more explanation about this [2].
I was trying to at least produce mentioned race, but couldn't.

Thank you in advance.
