In places where we have errno value set, such as after calling ptrace(), it makes sense to use pr_perror as it appends the errno string. This also fixes missing '\n' at the end (as pr_perror() adds it). In places where we keep using pr_err(), don't forget to have '\n'.

CRIU (Checkpoint and Restore in Userspace)
An utility to checkpoint/restore tasks. Using this tool, you can freeze a running application (or part of it) and checkpoint it to a hard drive as a collection of files. You can then use the files to restore and run the application from the point it was frozen at. The distinctive feature of the CRIU project is that it is mainly implemented in user space.
The project home is at http://criu.org.
