Comment 2 Martin Wilck 2023-08-31 10:05:22 UTC

The upstream commit is probably 

ced5fa8 ("mdadm: block creation with long names")

Comment 3 Martin Wilck 2023-08-31 10:26:36 UTC

@Coly, Intel has not identified an individual commit, unfortunately. Please double-check my assessment in comment 2. I have created a submission with that patch for SLE15-SP3 already.
