Whether we add it to a "pending" or not is just a question of whether
the migration is done right away, or left for later.

I left them for the benefit of any in-flight conflicts, or semantic
conflicts with out-of-tree.

I.e. in such a case you'd keep the other side, then apply the cocci
rule, and the result is a semantically correct merge of the two.

A bit. It doesn't slow it down by much, as these rules are the simplest
to execute, spatch can skip the file if the relevant tokens aren't found
in it.
