The bpf changes look ok and Andrii's approach is easier to grasp.
It's better to route bpf conversion to CLASS(fd,..) via bpf-next,
so it goes through bpf CI and our other testing.

bpf patches don't seem to depend on newly added CLASS(fd_pos, ...
and fderr, so pretty much independent from other patches.

Representation change and switch to accessors do matter, though.
OTOH, I can put just those into never-rebased branch (basically,
"introduce fd_file(), convert all accessors to it" +
"struct fd representation change" + possibly "add struct fd constructors,
get rid of __to_fd()", for completeness sake), so you could pull it.
Otherwise you'll get textual conflicts on all those f.file vs. fd_file(f)...
