[Gleb Smirnoff]

Author: glebius (src committer)
Date: Tue Jun  4 04:17:26 2019
New Revision: 503436
URL: https://svnweb.freebsd.org/changeset/ports/503436

Log:
  Unreverse the thread list for 'info threads' internal command. Now it
  will match the natural order of tailq, and thus output of 'ps' macro
  from tools/debugscripts/gdbinit.kernel.
