If you are using pmap or using strace and want to covert kernel address to function name then you can use the following technique.
First you need to install elfutils, if not installed.
dnf install elfutils
and after this you can use the following command
eu-addr2line -f -e /boot/vmlinuz-$(uname -r) <addr> #Example eu-addr2line -f -e /boot/vmlinuz-$(uname -r) 00007f36a8045000
