Sorry for the disagreement, for this one, I had to add the CONFIG_LIVEPATCH= to=20 then be able to call kallsyms_on_each_symbol(), as on 5.15, this function i= s=20 within a ifdef guard [1]. I suppose you do not want to add CONFIG_LIVEPATCH to default config, so I w= ill=20 try to find a way for this specific kernel! Did you get problems only for 5.15 kernel? Or others too? In the second case, can you please link me the problems and I will polish=20 everything. > thanks, >=20 > greg k-h Best regards. =2D-- [1]: https://elixir.bootlin.com/linux/v5.15.140/source/kernel/kallsyms.c#L2= 07
