Subject: coredump: use task comm instead of (unknown)
From: Jiri Slaby <jslaby@xxxxxxx>
If we don't know the file corresponding to the binary (i.e. exe_file is
unknown), use "task->comm (path unknown)" instead of simple "(unknown)" as
suggested by ak.
The fallback is the same as %e except it will append "(path unknown)".
