Hi,

I've showed syzbot coverage of the bpf subsystem to you recently, here
are the links I promised to send. If you go to:
https://syzkaller.appspot.com/upstream
coverage reports are in the Instances table in the Coverage column.
Choose a one with more coverage, e.g.:
https://storage.googleapis.com/syzkaller/cover/ci-upstream-linux-next-kasan-gce-root.html
(but be aware it's a 200MB html with whole kernel source code embed).
Then navigate to kernel -> bpf to see coverage on bpf sources.

The most useful things would be to identify parts that are not
currently covered, but can be covered from user-space and extend
syzkaller to cover them:

Thanks
