New Revision: 215044
URL: http://svn.freebsd.org/changeset/base/215044

Log:
  MFC 214682:
  Tweak the waitchannel messages for the dead lock detection kthread.  Use
  a shorter message (userland generally only sees the first 6 to 8
  characters) when waiting for the allproc lock.  Use "-" when idle to match
  the behavior of other kthreads.
