Thanks, yes that works.

Details;
I applied the patch to the v5.3.1 tag (diff attached), and built 3
kernels for testing.

v5.3.1 errors in seconds
v5.3.1_tobetter no errors
v5.3.1_neil no errors

The test is a rsync of a small database (24GB 2000 files) from a
remote server to a local spinning disk/lvm_devices=3/cryptsetup/ext4.
I also tested a simpler case and got no errors on any of the 3 builds
with local only rsync on spinning disk/mdadm_level=0_devices=2/ext4,
so either the network or storage stack are required to reproduce this
bug.
