svn commit: r214682 - head/sys/kern

[John Baldwin]

Author: jhb

New Revision: 214682
URL: http://svn.freebsd.org/changeset/base/214682

Log:
  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 math
  the behavior of other kthreads.
