Comment 2 Stanimir Varbanov 2024-03-28 10:59:41 UTC 
The fixing commit is part of 5.14 before branching (merged in v5.13-rc1) so the reference cannot be updated.
Comment 3 Gabriel Krisman Bertazi 2024-03-28 22:31:31 UTC 
Yep, the issue was introduced in 5.7 and fixed in 5.13 so this should be a nop for us.
Comment 4 Andrea Mattiazzo 2024-06-07 12:21:26 UTC 
All done, closing.
