Thanks for taking a look and testing! Thought I'd update you re status of some of the reports below. :-)

These are going away, fixes are already in -tip/-next.

The UBSAN object-size-mismatch warnings are going away, as fsanitize=object-size is broken/incomplete as it turns out -- UBSAN_OBJECT_SIZE will be removed from 5.17: https://bugzilla.kernel.org/show_bug.cgi?id=214861#c4 ... because all its warnings can also be covered by -Warray-bounds, which Kees is working on enabling.
Thanks, -- Marco
