100% agree. But in this case, dm-crypt sees a single BIO which gets split when

I'd like to see verification of this. People who send these kinds of
odd old kernel reports tend to have weird patches applied to their tree
as well.
Without an upstream reproducer that actually shows issues I think
this can be safely ignored.
Thanks for your suggestions.
I will try to make another patch of fault injection to reproduce it on qemu.
