It contains a 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. 63 */ 64 65 #ifndef _SYS_VFSOPS_H_ 66 #define _SYS_VFSOPS_H_ 67 68 #ifndef _SYS_ACL_H_ 69 #include <sys/acl.h> 70 #endif 71 72 struct vnode;
