[CCing the regression list, as it should be in the loop for regressions:

[TLDR: I'm adding this report to the list of tracked Linux kernel
regressions; the text you find below is based on a few templates
paragraphs you might have encountered already in similar form.

Thanks for the report. I see that the solution is already in sight, but
to ensure the issue doesn't fall through the cracks unnoticed, I'm
adding it to regzbot, the Linux kernel regression tracking bot (using
the commit ID the third patch Pablo mentioned, as the other two are
already mainlined):

#regzbot ^introduced 26b5a5712eb8
#regzbot title net: netfilter: kernel oops with netfilter:
#regzbot fix: netfilter: nf_tables: unbind non-anonymous set if rule
construction fails
#regzbot ignore-activity

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