I found them with the kunused scripts [1], which I wrote with LLM's help. The v1 cover letter [2] has more details on the scripts and how LLM was used. Changes in v2: - Split v1 [2] up by MM tree, as David suggested. These two patches are rebased on mm/core.git/for-next. Remaining patches will be sent separately. - No changes to the patches themselves.
