Are there? Well, not that I know of and that's why I'm being overly cautious. Maybe too cautious but a lot of hectic testing of last minute fixes in the past have taught me to take my time. And since it doesn't really matter when the patch goes in - there's always the next merge window - I would prefer to take our time and have it simmer in -next for max period. So yeah, 2.23 has been tested for a long time now and it is very likely that nothing would happen and if you think it's ok, then sure. Then if you happen to see urgent pull requests with build or some other fixes, at least you'll be prepared. :-) -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
