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.
