New Revision: 281696
URL: https://svnweb.freebsd.org/changeset/base/281696

Log:
  Initialize td_sel in the thread_init().  Struct thread is not zeroed
  on the initial allocation, but seltdinit() assumes that td_sel is NULL
  or a valid pointer.  Note that thread_fini()/seltdfini() also relies
  on this, but correctly resets td_sel to NULL.
