  Log:
  MFP4 (108673, 110519, 110874):
  - Currently LINUX_MAX_COMM_LEN is smaller than MAXCOMLEN, but in case
    this will change we have a buffer overflow. Apply some defensive
    programming to DTRT when this should happen.
  - Use copyinstr() instead of copyin where appropriate.
    * Fallback to copyin() in case of ENAMETOOLONG. [1]
    * Use the right source and destination (it was wrong before).
  - Use strlcpy instead of strcpy.
  - Properly lock the read case (PR_GET_NAME) like the write case.
