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