Author: jhb Date: Tue Nov 2 18:34:31 2010 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.
