Leveraging results from 5.4.0-55, no regression were observed, results are available here:

There are 3 verifications left. Two which I would see non-critical. The 3rd (CIFS) might have bigger impact, but its an internal submission and using the proposed kernel I did not notice issues in accessing Samba volumes.
