Yes, these should be reverted from 5.10 via 5.10.1:
e0910c8e4f87 dm raid: fix discard limits for raid1 and raid10
f075cfb1dc59 md: change mddev 'chunk_sectors' from int to unsigned
They were also both marked for stable@, and I just got email stating
that you've staged them both for 5.4 and 5.9, but they shouldn't go to
stable@. We need to reassess and fix during 5.11.
I'll now respond with my Nacked-by to each patch email relative to these
commits.
Thanks,
Mike
