I'll see if I can reproduce this. I'm assuming samba is using buffered
IO, and it looks like it's reading in chunks of 1MB. Hopefully it's
possible to reproduce without samba with a windows client, as I don't
have any of those. If synthetic reproducing fails, I can try samba
with a Linux client.
I attached the logs from both a Windows 10 client and a Linux client
(kernel 5.11.0).
