The umap filesystem directly references a function "null_bypass" belonging
to the null filesystem. But if the nullfs was loaded as a LKM, too, it
won't find the symbol. This used to work before the Lite2 merge.

Try to load nullfs and umapfs as LKMs.

Either remove reference to "null_bypass" or the nullfs LKM.
