When I try make to the mainline(staging-test) kernel it ends up with the error

Failed to generate BTF for vmlinux
Try to disable CONFIG_DEBUG_INFO_BTF
make: *** [Makefile:1162: vmlinux] Error 1

So, when I google it I found that to install dwarves, but still the error coming.

What distro are you using? What version? Just guessing, it's an older version of Linux and doesn't have the latest software versions. You may need to update your Linux installation to be able to get packages that are new enough to work with the latest kernel versions.

Here is the man page for pahole: https://linux.die.net/man/1/paholehttp://

It appears that Ubuntu 20.04 still has dwarves 1.15 for some reason. The current version is 1.17, and is available in the Debian repositories, both Bullseye and Sid. I think you need to get the latest version, which is not in Ubuntu 20.04.
