As far as I know, the model was written originally by Dave Jones, with
further changes from myself and, I think, Colin Ian King.

I thought it was visible through the Coverity dashboard, once you're
logged in:
https://scan.coverity.com/projects/linux-next-weekly-scan?tab=analysis_settings
(See 'Modeling file loaded [View]')

Regardless, I keep a copy in git since I'd been tweaking it (mostly to
no meaningful benefit: the model file doesn't work with macros, which is
where the bulk of the false positives in Coverity come from):
