Hi, everybody, I have some questions about FS vnode operations. I found the filesystems always declare vnode operations by "VNODEOP_SET" more than once. For example: In DEVFS: VNODEOP_SET(devfs_vnodeop_opv_desc); VNODEOP_SET(devfs_specop_opv_desc); In FFS: VNODEOP_SET(ffs_vnodeop_opv_desc); VNODEOP_SET(ffs_specop_opv_desc); VNODEOP_SET(ffs_fifoop_opv_desc); Why? Why can not the kerenel use only "devfs_vnodeop_opv_desc" or "ffs_vnodeop_opv_desc"? Another words, I want to know the difference among those "VNODEOP_SET" in one filesystem. Thank you!
