It doesn't works !  it even worse that with the other patch, as i was able to block everything with just starting 2 clients !
echo 0  kills it, i can restart a client, set up an array, stop the client...

No changes, client is not killed, md can't be stopped.

then starting a new client leads to kernel oops :

Unable to handle kernel NULL pointer dereference at virtual address 0000000c
