[PATCH V33 27/30] lockdown: Print current->comm in restriction messages

[Matthew Garrett]

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
