There was a change to bio_alloc_bioset:
https://lore.kernel.org/all/20220727161012.364032637@linuxfoundation.org/
Thanks, I've now dropped that one and some others and will push out a -rc2 in a few minutes...
Sorry about the hassle. It was only tested on ext4 fs.
Tim, The fix consisted of two patches. I'm just curies if it helps if you apply this on top:
https://lore.kernel.org/all/20220727161012.411398366@linuxfoundation.org/
That was "on top" when others reported it failing. And there were at least 2 other needed fixes on top of that :(
Please work to make a full set of patches that are tested and I will be glad to reconsider, otherwise this just isn't going to be an issue for 5.10.y that we need to worry about. If you are concerned about this problem, use 5.15.y or newer please.
thanks,
