Author: jhb Date: Tue Nov 9 18:46:09 2010 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.
