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.
