Mm.. these are not critical indeed, but patches 1 and 3 do fix a crash.
Perhaps those should had been a series on their own. 

We'll recalibrate :)

 Hi,
 Because the "__printf()" attributes were used only where the functions are
 implemented, and not in header files, the checks have not been enforced on
 all the calls to printf()-like functions, and a number of errors slipped in
 bpftool over time.

 This set cleans up such errors, and then moves the "__printf()" attributes
 to header files, so that the checks are performed at all locations.

Ok, thanks for explaining. I'll consider submitting this kind of patches
to bpf-next instead in the future.

Yes. I don't see the _fix_ part in there.
Looks like cleanup to me.
I've also considered to push
commit d34b044038bf ("tools: bpftool: close prog FD before exit on
showing a single program")
to bpf-next as well.
That fd leak didn't feel that necessary to push to bpf tree
and risk merge conflicts... but I pushed it to bpf at the end.

Thanks Alexei!

I noticed the set was applied to the bpf-next tree, and not bpf. Just
checking if this is intentional?

Applied. Thanks
