SubjectRe: [RFC][PATCH v2 21/34] merging pick_link() with get_link(), part 4
Ok, so far I haven't seen anything bad. But I keep noticing these odd
stylistic things...

What?

Those "else" statements make no sense.

Each if-statement has a "return" in it. It's done. The else part is
not adding anything but confusion.

IOW, this should be

if (!err)
return NULL;
if (err > 0)
return get_link(nd);
return ERR_PTR(err);

with not an 'else' in sight.
