Please take the following 2 commits from 6.5 to 6.1-LTS. They're
already present in 5.10, 5.15, but seemingly were missed from 6.1.
They apply cleanly and compile for me.
873f50ece41a ("md: fix data corruption for raid456 when reshape
restart while grow up")
010444623e7f ("md/raid10: prevent soft lockup while flush writes")
