This line magically appeared, and makes it hard to apply the series
without hacking the patches manually. Going forward, please supply a
base tree commit to the series (or a link to a complete git tree).


A rebase version has been resend as follow:

https://lore.kernel.org/bpf/20221220021319.1655871-1-pulehui@xxxxxxxxxxxxxxx/

Yes, but with the same issue:
https://lore.kernel.org/bpf/20221220021319.1655871-4-pulehui@xxxxxxxxxxxxxxx/

The "is_main_prog" line is still around in the resend.


Oops, something was left when debugging mixing bpf2bpf and tailcalls. Sorry, will send v2.
