Judging from the fact that
(1) the only caller calls this function in this fashion based on the
setting of "cannot-trust" bit,
(2) this and the other function the only caller calls share the
same code in their beginning part, and
(3) the body of the if() statement here duplicates the code from
collect_all_attrs(),
I smell that a much better split is possible.
Why isn't this all inside a single function collect_all_attrs()?
That single function may no longer be collect_ALL_attrs, so renaming
it to collect_attrs() is fine, but then that function may have this
if () to initialize all of them to ATTR__UNKNOWN or do the else part
we see below, and when organized that way we do not need to have
duplicated code (or split_path() helper function), no?
