  Modified files:
    sys/kern             vfs_subr.c 
  sync_vnode() has some messy code about locking in order to deal with
  mount fs needing Giant to be held when processing bufobjs.
  Use a different subqueue for pending workitems on filesystems requiring
  Giant. This simplifies the code notably and also reduces the number of
  Giant acquisitions (and the whole processing cost).
