commit 153446ecd740702af00cf9b09d8cd39f6d397dd3 Author: Jean-Sébastien Pédron <[email protected]> AuthorDate: 2026-08-15 18:31:46 +0000 Commit: Jean-Sébastien Pédron <[email protected]> CommitDate: 2026-09-07 18:27:30 +0000 linuxkpi: Add `split_page()` This function is supposed to split large pages into an array of `PAGE_SIZE`-sized pages, with correct refcounting. This is apparently used to allow some drivers to free a part of a large page only. I don't think we use large pages in linuxkpi. Therefore, this new function is curently a no-op. The DRM drivers TTM memory manager started to use it in Linux 6.15.
