The branch stable/15 has been updated by dumbbell: URL: https://cgit.FreeBSD.org/src/commit/?id=34a73bf20c9694ca1d511f2cfeb2b7e5217c36a7 commit 34a73bf20c9694ca1d511f2cfeb2b7e5217c36a7 Author: Jean-Sébastien Pédron <dumbbell@FreeBSD.org> AuthorDate: 2026-04-21 00:32:18 +0000 Commit: Jean-Sébastien Pédron <dumbbell@FreeBSD.org> CommitDate: 2026-04-29 21:04:04 +0000 linuxkpi: Define `DIV_U64_ROUND_UP()` It is the same as `DIV64_U64_ROUND_UP()` but takes a 32-bit integer as the divisor. The amdgpu DRM driver started to use this in Linux 6.12.x.
