0961aa92 38 * The vop_ops structure vectors all access to a filesystem. It contains a
2d3e977e
MD
39 * fixed set of vectors which are 'compiled' by the vnodeopv_entry_desc
40 * array that is typically declared in "vfs/blah/blah_vnops.c".
41 *
42 * In DragonFly the ultimate goal is to thread the VFS, which means that
43 * the dispatch functions will eventually be called from the context of
44 * a management thread rather then directly called by a process. This
45 * requires us to divorce direct process dependancies (in particular ioctl
46 * and UIO's). In addition, it is our intention to implement kernel
47 * level cache management and coherency in the vop_*() interfacing
48 * layer.
49 *
50 * The number of management threads will depend on the VFS. The idea is
51 * to give a high performance VFS such as UFS at least one thread per cpu,
52 * and a low performance VFS such as CD9660 perhaps just one thread period.
53 * Blocking issues within the management thread are up to the VFS itself,
54 * but DragonFly will introduce a layer above the VFS to handle cacheable
55 * requests without having to enter the VFS (e.g. by making attribute
56 * and VM object information a permanent fixture of the vnode structure
57 * and accessing them directly).
58 *
59 * THE VOPOPS VECTORS SHOULD NEVER BE CALLED DIRECTLY! Instead always use
60 * the kernel helper procedures vop_*() to call a vopop. The kernel
61 * helper procedure will be responsible for handling the DragonFly messaging
62 * conversion when it occurs.
