svn commit: r183690 - head/sys/kern

[Robert Watson]

Author: rwatson

New Revision: 183690
URL: http://svn.freebsd.org/changeset/base/183690

Log:
  Remove stale comment (and XXX saying so) about why we zero the file
  descriptor pointer in unp_freerights: we can no longer recurse into
  unp_gc due to unp_gc being invoked in a deferred way, but it's still
  a good idea.
