  36  * The vop_ops structure vectors all access to a filesystem.  It contains a
  37  * fixed set of vectors.
  38  *
  39  * In DragonFly the ultimate goal is to thread the VFS, which means that
  40  * the dispatch functions will eventually be called from the context of
  41  * a management thread rather then directly called by a process.  This
  42  * requires us to divorce direct process dependancies (in particular ioctl
  43  * and UIO's).  In addition, it is our intention to implement kernel
  44  * level cache management and coherency in the vop_*() interfacing
  45  * layer.
  46  *
  47  * The number of management threads will depend on the VFS.  The idea is
  48  * to give a high performance VFS such as UFS at least one thread per cpu,
  49  * and a low performance VFS such as CD9660 perhaps just one thread period.
  50  * Blocking issues within the management thread are up to the VFS itself,
  51  * but DragonFly will introduce a layer above the VFS to handle cacheable
  52  * requests without having to enter the VFS (e.g. by making attribute
  53  * and VM object information a permanent fixture of the vnode structure
  54  * and accessing them directly).
  55  *
  56  * THE VOPOPS VECTORS SHOULD NEVER BE CALLED DIRECTLY!  Instead always use
  57  * the kernel helper procedures vop_*() to call a vopop.  The kernel
  58  * helper procedure will be responsible for handling the DragonFly messaging
  59  * conversion when it occurs.
