-/* fix_bad_parent() : called if this dentry's vcache is a root vcache
- * that has its mvid (parent dir's fid) pointer set to the wrong directory
- * due to being mounted in multiple points at once. fix_bad_parent()
- * calls afs_lookup() to correct the vcache's mvid, as well as the volume's
- * dotdotfid and mtpoint fid members.
- * Parameters:
- * dp - dentry to be checked.
- * credp - credentials
- * vcp, pvc - item's and parent's vcache pointer
- * Return Values:
- * None.
- * Sideeffects:
- * This dentry's vcache's mvid will be set to the correct parent directory's
- * fid.
- * This root vnode's volume will have its dotdotfid and mtpoint fids set
- * to the correct parent and mountpoint fids.
