bpfilter: read fail 0

[Vincent Li]

Hi,

Sorry if this is the wrong list, I installed
https://kernel.ubuntu.com/~kernel-ppa/mainline/v6.1.10/ on Ubuntu
20.04. I have firehol running with iptables rules, the kernel emits
noise log messages like below all the time, google this message, it
appears the issue has been fixed in the upstream mainline kernel, I am
wondering if Ubuntu PPA kernel could address this issue.
