It contains a 37 * fixed set of vectors. 38 * 39 * In DragonFly the ultimate goal is to thread the VFS, which means that 40 * the dispatch functions will eventually be called from the context of 41 * a management thread rather then directly called by a process. This 42 * requires us to divorce direct process dependancies (in particular ioctl 43 * and UIO's). In addition, it is our intention to implement kernel 44 * level cache management and coherency in the vop_*() interfacing 45 * layer. 46 * 47 * The number of management threads will depend on the VFS. The idea is 48 * to give a high performance VFS such as UFS at least one thread per cpu, 49 * and a low performance VFS such as CD9660 perhaps just one thread period. 50 * Blocking issues within the management thread are up to the VFS itself, 51 * but DragonFly will introduce a layer above the VFS to handle cacheable 52 * requests without having to enter the VFS (e.g. by making attribute 53 * and VM object information a permanent fixture of the vnode structure 54 * and accessing them directly). 55 * 56 * THE VOPOPS VECTORS SHOULD NEVER BE CALLED DIRECTLY! Instead always use 57 * the kernel helper procedures vop_*() to call a vopop. The kernel 58 * helper procedure will be responsible for handling the DragonFly messaging 59 * conversion when it occurs. 60 */ 61 62 #ifndef _SYS_VFSOPS_H_ 63 #define _SYS_VFSOPS_H_ 64 65 #ifdef _KERNEL 66 #ifndef _SYS_ACL_H_ 67 #include <sys/acl.h> 68 #endif 69 #ifndef _SYS_BUF_H_ 70 #include <sys/buf.h> /* buf_cmd_t */ 71 #endif 72 #ifndef _SYS_FCNTL_H_ 73 #include <sys/fcntl.h> /* AT_EACCESS */ 74 #endif 75 76 struct syslink_desc;
