[Note: this mail contains only information for Linux kernel regression

then easy to spot and filter out. The author also tried to remove most

Thanks for the report. To be sure below issue doesn't fall through the
cracks unnoticed, I'm adding it to regzbot, my Linux kernel regression
tracking bot:

#regzbot ^introduced c86df29d11df
#regzbot title net/bpf: BUG: unable to handle kernel paging request in
bpf_dispatcher_xdp
#regzbot ignore-activity

Ciao, Thorsten (wearing his 'the Linux kernel's regression tracker' hat)

P.S.: As the Linux kernel's regression tracker I deal with a lot of
reports and sometimes miss something important when writing mails like
this. If that's the case here, don't hesitate to tell me in a public
reply, it's in everyone's interest to set the public record straight.
