When a parent directory lookup is done at the root of a snapshot mounted under .zfs/snapshot directory, we need to look up that directory in the parent filesystem. We achieve that by doing a VOP_LOOKUP operation on a .zfs vnode with "snapshot" as a target name. But previously we also passed ISDOTDOT flag to the lookup and, because of that, the lookup actually returned the parent of the .zfs vnode, that is, a root vnode of the parent filesystem.
