New Revision: 324445
URL: https://svnweb.freebsd.org/changeset/base/324445

Log:
  When showing the sleepqueues from the in-kernel debugger,
  properly dump all the sendqueues and not just the first one
  
  History:
  It appears that in the commit which introduced the code,
  r165272, the array indexes of "sq_blocked[0]" and "td_name[i]"
  were interchanged. In r180927 "td_name[i]" was corrected to
  "td_name[0]", but "sq_blocked[0]" was left unchanged.
