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. 62 */ 63 64 #ifndef _SYS_VFSOPS_H_ 65 #define _SYS_VFSOPS_H_ 66 67 #ifndef _SYS_ACL_H_ 68 #include <sys/acl.h> 69 #endif 70 #ifndef _SYS_BUF_H_ 71 #include <sys/buf.h> /* buf_cmd_t */ 72 #endif 73 #ifndef _SYS_FCNTL_H_ 74 #include <sys/fcntl.h> /* AT_EACCESS */ 75 #endif 76 77 struct syslink_desc;
