* Add support function vfs_get_mount_point(), so a file system can get its own mount point (i.e. the node it covers). Re-added fs_mount::covers_vnode for that purpose -- the root node isn't know to the VFS before the mount() hook returns. * Add function vfs_bind_mount_directory() which bind-mounts a directory to another. The Vnode::covers/covered_by mechanism is used, so this isn't true bind-mounting, but sufficient for what we need ATM and cheaper as well. The vnodes connected thus aren't tracked yet, which is needed for undoing the connection when unmounting. * get_vnode_name(): Don't use dir_read() to read the directory. Since we have already resolved vnode to the covered vnode, we don't want the dirents to be "fixed" to refer to the covering nodes. Such a vnode simply wouldn't be found. |
