Subject[PATCH V34 29/29] lockdown: Print current->comm in restriction messages
From
Print the content of current->comm in messages generated by lockdown to
indicate a restriction that was hit. This makes it a bit easier to find
out what caused the message.

The message now patterned something like:

Lockdown: <comm>: <what> is restricted; see man kernel_lockdown.7
