Thank you for the update.
kernel_symbol_exists() is better.
And it might be also good to check it out of the loop only once.
Lianbo, what do you think?
int crash_notes_exists = kernel_symbol_exists("crash_notes");
Fine to me, we can take the above changes. Kazu.
And also thank you for sharing the steps on how to reproduce, HATAYAMA. This definitely helps me a lot.
The v2 series looks good to me, and works fine on aarch64, so: Ack.
Thanks.
Lianbo
Anyway, we can change it when merging, so for the series,
