New Revision: 215750
URL: http://svn.freebsd.org/changeset/base/215750

Log:
  taskqueue: drop unused tq_name field
  
  tq_name was used write-only and besides it was just a pointer, so it
  could point to some garbage in a temporary buffer that's gone.
  This change shouldn't change KPI/KBI as struct taskqueue is private to
  subr_taskqueue.c.
  If we find a need for tq_name it can be resurrected at any moment.
  taskqueue_create() interface is preserved for this purpose.
