Re: GSOC - valgrind-hurd queries

[Subhashish Pradhan]

Hello,

I've successfully passed the final evaluations for the project. Thanks
for your mentor-ship.
This week I'll take a break to plan the next steps for this project.

For the code submission, the patch set will not include the "teaching
of the link flags".

Do you think I could mention this project in my CV after I complete
the port as a part of the work done for the GNU Project?

Sincerely,
Subhashish Pradhan
