Thanks for v2! Patch itself looks good to me. I always add another `Link:` tag to the last version of the patch at the time of applying, so the message might be a bit confusing. Feel free to keep the link to the previous discussion but I'd rather just repeat a bit more of what we discussed (e.g. fix rcu not being dereferenced cleanly by using the task helpers as suggested) rather than just link to the thread Sorry for nitpicking but I think commit messages are important and it's better if they're understandable out of context, even if you give a link for further details for curious readers, it helps being able to just skim through git log. Either way I'll include the patch in my test run today or tomorrow, had promised it for a while... Cheers, -- Dominique
